I don't understand what you would gain by replacing Twitter and Facebook. The incentives and structures that created them are here to stay. Anyone who thinks their open source pet projects wouldn't face the same problems Twitter has at the scale 300M active users is just being woefully ignorant of politics at play here and still thinks Twitter can be built in a weekend.
In 2016, you had a guy jokingly claim that he was ripping republican ballots in Ohio. This tweet spread like wildfire, and caused an unimaginable headache for the secretary of state as the right-wing media went wild on the story. I'm not surprised Twitter is taking such heavy handed action given that they will be directly in the cross hairs if a story like that ever happens again. No "replacement" would be immune from this issue.
