The reason for the complaining up front is that many of us have been through this with a variety of lame arguments before. I had a bug that seemed to be introduced for my browser only when they changes the log in registration a few weeks back. The bug went away last night.
Some of the things they want to do seem to be with choices in the user profile. If they succeed in doing that, then folks may not complain long, but if they fail the sky will be falling (again!).
The last change wasted a lot of space on the screen and was time consuming to navigate. For regulars to the forums, it was a bit time sink. Part of the problem was all of the extra little things that were thrown in about the poster and such, that could be left to a click. I find the 1 line post label as above to work fine. I don't need a nonsense picture or life history. I am content to click on the name if I wanted such information.
Those are just a few of the issues, but the history and related fear of what is to come has lead to this complaining. Basically, many Adobe forum users do not trust the power that be.
