I agree, for the most part, although I think there were not only mismanagement of the company behind 2nd Edition AD&D, but also problems in the game that killed it.
The only edition that really "failed" in any sense was 2nd Edition, in my opinion, and 3rd Edition is treading the line on some of the same problems.
D&D is a good thing, right now, but 3.5 burned a lot of independent publishers, and depending on how 4th Edition is handled, I can see 3rd Edition - which is a game I like, and enjoy playing - being an even worse mistake if they aren't careful.
