content: It does not make sense to completely abandon a platform that has lots of eyeballs.  The correct move is to create or use tools that allow you to replicate your content across platforms.  This helps build competing platforms and let's you continue to get most of your message out.  If your message may be questionable on one platform, then don't post it.  If people like your content and want the missing content, they'll start using the alternative platforms.  The censoring platforms lose eyeballs, the alternative platforms get more eyeballs, and you still get the maximum benefit from all existing platforms.
