Some of the photos I have looked at here, show some filthy sensors. It would take multiple swabings to clean them entirely imo. Some of the small scratches might also be from a swabbing, and some look like streaking.
Some dust can get welded onto the sensor, and that is why its a good idea to clean them periodically.
Did I ever tell you how much I hate cleaning sensors? lol
Using a rocket blower only to get sh*t on the upper screen or on the viewfinder itself.
Cleaning that can be a headache for sure, but it can be done if your careful.
Normally I shoot most of my lenses wide open or close to it, and dust has no bearing if its not showing up in the raw file.
Dust & dirty sensors is nothing new, and nothing that has not been talked about before. A whole industry has been built on manufacturing and selling Swabs, Brushes, Pens, Fluids and more for years to keep the sensor clean for all brands of cameras.
Anyway, here are two photos of my sensor at F/22 ISO 100 with the 35mm II
I have a few spots that need attention, but only if I was going to shoot at F/22 again in the future. 
I personally don't see the lines you talk about, and if they do exist by manipulating the image with Hdr or dehaze or a combination of both it is still a non-issue if you fine them by doing this. If it ain't broken, don't fix it....
Some people like to manipulate their images in post, and some HDR have that Frankenstein look to them as I like to call it, which will show every little dust spec if you push it too far. Personally I don't like the dehaze filter in PS and find I can do the same by adjusting other settings that don't seem to alter the image. Same goes for pushing the clarity slider which alters the image imo.
Only reason for coming back and posting is due to you thinking all 1D users ran away. Too bad you have had all the problems with your gear, but good to know Canon replaced it for you. Good of you trying to get the word out as well.

Can you honestly say from looking at the photos people have posted with the amount of crud on their sensors that it's normal? I have seen some bad 5D sensors in my time, but no where near as bad as what happens to these 1DX2 sensors. This is Nikon D600-level bad.
You have to remember as well, that even though there's a whole industry of cleaning products for sensors, the products themselves carry risks of causing damage. Extremely dirty sensors, like what we are seeing in this thread, will carry a higher risk of cleaning because there's more particles on them, and is yet another reason why this is a problem that needs addressing. This is not normal for any other model of camera produced by Canon.
As far as the argument goes about manipulating the image via Dehaze, HDR, etc...well, it is actually still an issue. If you convert an image to a contrasty black and white photo, for example, it will essentially do exactly same thing, and both sensor lines and dust will appear more readily. Furthermore, I often push a portion/area of a photo quite heavily using Dehaze, or by adjusting the contrast, and I'd really rather not have to deal with a manufacturing defect under any circumstance.
The argument not to over manipulating photos doesn't hold water with me. There's many photographic styles today, with different editing techniques to meet different peoples' tastes. Art is, after all, subjective. I would hope that the one thing we can all agree on is that a flagship camera that commands a $6000 price tag should be free from defects, such as sensor lines and excess oil being splattered around more readily than on other models.

Can you post a full sized shot, or link to one of your RAW files? It's impossible to see if there are any defects from such a compressed image.
