There was never really a coherent anti-2e movement. There was a rather strenuous marketing effort coinciding with the release of 3e to create antipathy for it, to sell 3e books. 2e was overwhelmingly welcomed by groups that were playing AD&D and keeping up with news and events around the game. Many of the elements that didn't get moved from 1e were incredibly unpopular. Monks and assassins were widely disliked, as was anything from Unearthed Arcana. Weapon specialization was considered suspect (though it was widely used to give the fighter some oomph), and greatly toned down. The dual-wielding, stealthy ranger was designed to move rangers away from heavy armor use and the bard was redesigned because the previous version was considered to be unplayable.
2e was pretty much designed by taking 1e and incorporating the broad consensus that existed at the time. In fact, some more experimental elements that were announced for 2e were pulled back in favor of keeping continuity with 1e. The biggest one of these was the toning down of the promised "group" concept, where every class was part of a meta-class template that could be used as the basis for new of modified classes.
