Canon cameras make great photos now and in the past. They are a little easier to use now than past models.
My camera still makes photos just as good as it did when I bought it. Better, in fact, because I have progressed.
If you bought the cameras at the time and didn't quickly return them as inadequate then, then they are not inadequate now.
If you don't like current offerings, don't buy.
The percentage of people who actually require the latest and the greatest for producing money is very very small and unlikely to include whiners on forums. Pros who reach that decision just buy what they feel they need, quietly and without a lot of fuss, without having to have their egos massaged in public by making dramatic pronouncements.
It amazes me what a high percentage of people are prevented from making good photos by some perceived lack of automation. The only other alternative I can see is that they are so terrifyingly awesome photographers that they are held back by their equipment in creativity; but I think it is highly unlikely that would apply to any of the whiners.
