Can you give some examples? Not having been a 2e player, I never saw any of that marketing...only the run-up marketing for 3e to lapsed players.
I recall a number of uncomplimentary things said by brand management at the time, and most of all the suggestion that AD&D had alienated/lost players. In fact, AD&D 2nd lasted for over a decade -- about as long as 1e -- and was the top selling RPG for the entire time, with the exception of a brief period right after the release of Vampire: The Masquerade Revised. "Dead as a product line?" Hardly. In the state TSR was in, even success couldn't save them from several cycles of bad corporate decisions. It really isn't AD&D 2nd's fault that TSR had no idea what to do with Dragon Dice, for example. And most gamers have never even *heard* of TSR's internet policies. Much of this is overblown by the medium we're talking in, which is dominated by folks who've been online since the 90s when this all went down.
(In an interesting contrast, consider WotC's failed entry into the top of the RPG tier. Released while the company was growing into a behemoth by folks that are well-respected around her, including cool, with-it management, Everway still underperformed. Just as TSR's failings are not necessarily in lockstep with AD&D, WotC's massive success in the 90s did not infect Everway.)
In short, AD&D 2nd had an excellent run and you'd be hard-pressed to argue that 3e would have aged more gracefully after 12 years.
