It's an interesting product offering.
Canon doesn't sell their $300 adapter with a clear filter, you have to go buy that for an additional $129. So apples to apples for a CPL and clear filter: Canon = $429, BTP = $329
BTP has a widely more useful line of drop-in filters, Canon doesn't.
Regarding trading in old Canon adapters, in this day and age, with the hardships of getting any kind of RF adapter, nobody would trade theirs in. They would make at least what they paid, probably 50% more than what they paid, right now on the used market.
I wonder what they would give me for my Meike RF adapter I paid $55 for, lol!

It's great to see the wide range of drop in filters that Breakthrough Photography is offering, including a variety of plain ND filters, 10-16 stop variable ND, combination ND and CPL, IR, etc. Hopefully the lens mount fit and build quality of their adapter is close to the Canon one, as I haven't been too impressed with the build quality of most of the 3rd party EF to R adapters so far.
In terms of the trade-in of old adapters, it's a little unclear if you just send back the Canon drop-in filter adapter, or also the filter itself (CPL or Variable ND). The Canon Variable ND costs $100 more than the CPL, so it's odd that they would give the same trade-in amount for both. Also, the Breakthrough Photography drop-in filter adapter for $199 doesn't come with a CPL or Variable ND, so it wouldn't be a straight swap to buy their adapter if you also have to give up the filter.
If you get to keep the Canon filter, a $149 trade in for just the adapter, is not such a bad deal.
With the current lack of supply of the EF to R adapters, the used prices are pretty high, but this may not always be the case. With an adequate supply of these adapters available, then the used prices will likely drop. For example, $69 for a used EF to R adapter (that goes for $99 new) is much more in line with what you would expect used prices to be for this type of accessory (around 70% of new price).
By the time these Breakthrough Photography adapters start shipping in volume in a couple of months, which is when you'd have to send in the old adapter if you want the rebate, the used market for the Canon adapters might look different, and the trade-in offer could make more sense.

Don't like the fact they are different from canon. breakthrough filters will likely be better optically. The canon nd is being reported and not truely neutral. A real plus for the wide angles that have bulbous fronts that require gigantic filters and adapters. The canon adapter would be better if it had a version that allowed you to screw in different filters like the super telephotos. Same for breakthough where you could just replace the filter and not the drop in frame as well. I stack my filters with stack caps. very compact and well protected. This will not be as compact.

The Canon comes with a CPL, whereas the Breakthrough only comes with a clear filter (and only the first 500 orders include it).

Kolari Visions came out with a bunch of Filters for Canon. Some are on backorder and some are in stock. And if I'm not mistaken they make the adapter and sell it for $149.00

I called that out in my post. To get both, BTP is $100 cheaper ($300+129 vs $200+129).
The reason it matters regarding the clear filter being included is that many are willing to buy this Canon adapter for their EF to RF conversion since there aren't any Canon adapters (any of the other 2 types) to be found, and if they can get a drop in UV/clear filter, they would buy that just to augment their R5/R6 purchase.
I mean for pete's sake, people are willing to spend $180 for the plain adapter now on ebay and amazon which is almost twice the list price.

Can the adapters be used without any filter mounted into the holder (or do the filters come mated to the holder)? If not, I'm not clear on what benefit a clear adapter would provide, outside of maybe preventing dust from getting into the camera when changing EF lenses while the adapter is mounted to the camera.

You can you the adapter without a filter but then you are opening a whole can of worms. The reason for the clear filter is to keep the dust and dirt out of your camera because if you did not have a filter inside you would have a huge opening. If you really wanted to use it without the filter you would have to put tape over the opening to keep the dust and dirt out. Picture you are on a beach and it is very windy and you had no filter when you got home your camera would be full of sand.

I was thinking there's a filter holder available for purchase without a filter installed. If so that would be prevent the scenario you described. If not then I agree with you that it would be an issue.

There isn't any such thing other than little 3d printer guys out there that might do this, unfortunately. However, one could use silly putty to close that gap easily and it wouldn't gum anything up.
$130 for a clear small diameter filter is quite ridiculous on Canon's part though.
You might be thinking about the drop in filter system for some of the L lenses, but I am quite sure none of those fit the RF adapter.

If I’m not mistaken I believe that is why they have the clear glass filter..
p.1 #16 · Break Through Photography announces new EF to RF drop in filter adapter
I believe the filters themselves are actually compatible with the Canon adapter....it was listed that way a few weeks ago on CanonRumors before the same company announced their own adapter. Further makes one wonder why anyone would trade in....
I do not think you can really use the filter adapter with no clear filter installed. I believe the filter adapter is a slightly different length to account for the back focus distance change with the extra piece of glass. So just pulling the filter and taping over the opening could affect your ability to focus some lenses.

I believe the glass is part of the optical formula like in a super telephoto. Not sure how big a difference it really makes but is required for best results.
p.1 #18 · Break Through Photography announces new EF to RF drop in filter adapter
I just finished a chat on Breakthrough's site and I asked specifically whether their drop in filters would work on the canon lenses that use drop in filters. Their rep said yes.
Maybe I should ask if their filter "holder" is directly compatible too.
p.1 #19 · Break Through Photography announces new EF to RF drop in filter adapter
Follow up. I just got off another chat with Breakthrough. Here's their precise response regarding whether the filter adapters are compatible with existing Canon ones:
"Our filters are compatible with the Canon drop-in filter adapter as well as our upcoming drop-in filter adapter." That still leaves open the possibility that the adapters could be different, even though the filters can be used interchangeably. Hmmm. Looks like I have to ask again.

The lens was not designed with any thoughts of using it with the adapter.
If by optical formula you mean the equation for the focus shift to the rear (closer to the imaging plane) due to the glass plate, an estimate would be (n-1)/n or about 1/3 of the thickness of the filter if the refractive index is 1.5. I would hope that the EF-RF adapter tube would have a slightly shorter distance than needed so that the prime lens would always focus to infinity even if different filters are used. For example a polarizer is typically comprised of two pieces of glass surrounding the polarizing material.
