Tl;Dr: I'd give about 80% likelihood to a wave of content and community toxicity going forward. (Edit: I assume the question is about using Twitter; the answer indirectly addresses working for Twitter as well) Established communities are highly sensitive to tectonic shifts in the underlying power structures. The new management has come with an agenda to stir said structures, but does not make the impression of being particularly sensible or skilled at nurturing communities at large. In other words, as soon as a community reaches a certain size, only very persistent policing can keep it bearable for members. Tampering with the moderation will likely upset that, and by the time the new management learns the ropes, it is likely that most communities will disband and move elsewhere. Hence my conclusion. Proper disclosure: I don't have a Twitter account.
