It is so far a slightly different situation. First it gets revenue directly by the users instead of advertisers. This changes everything at a fundamental level.

Second, the type of community is much different. The communities using the full feature set are generally limited in scale one way or another. The issues with Facebook, Twitter and reddit arose also because there is a gigantic userbase which interacts with each other. Toxic policies are more likely to be forcefully accepted due to the massive social inertia.

Type of content hits differently. As a lot of communication is real time, or moment to moment, there is less lost value if things go haywire. Now this absolutely does not apply for servers which directly act as a forum replacement run by the companies themselves. Some use it as a website replacement for some reason which is also a terrible idea.

I think a future migration will be a lot more fluent and less hurtful overall. The moves away from TeamSpeak, Ventrilo, Skype were never impactful. With the monetization model I also view it as less probable.
