No, the community itself did that all on its own long before Blizzard did anything to further the pain. This game was going in the toilet before the LFD and the LFR, as well as all the cross-realm features they instituted in the game. The elitist and intolerant as well as the anti-social people are to blame for this community going in the tank. The real world is a far different place and animals since WoW first came on the scene in 2004. Just go into any game (other than a single player) and at any level and you will see what this retail version, not private Classic version will be ultimately be turned into and it will have absolutely nothing to do what Blizzard will have done.
I personally can't wait, after about six months to a year people like yourself will be whining how toxic Classic is. It has always been the community that has driven this train and the forums themselves prove just how toxic WoW has been from a community standpoint for year. Sadly though, WoW is not alone in the every toxic department. There are still part of the community that has managed to endure over the years, but they do not make up the bulk of the community any longer. Cross-realming has simply made the toxic level worse with every sh*t head from every populated realm having literal access to all the other attached realms.
