I haven't actually noticed much change there. Sure, people seem to be angry about all kinds of things, but that's the normal over on twitter. The core functionality of 'post tweet' and 'see tweets others have posted' seems unaffected for me and every user I follow.
I don't really see what everyone is angry about. "User XYZ did X controversial action and got banned for it" is of no interest to me, partly because I am not interested in User XYZ, and partly because the sorts of things I use twitter for don't revolve around seeing the spread of whatever the next activist thing is.
