To the degree FB and Twitter receive ad revenue based on posting volume, banning Trump is shooting their revenue in the foot ... or maybe knee capping it. Trump will find other means to bypass the MSM's and social media giants' blocks. FB, Twitter, and many MSM outlets will struggle, possibly fail, at trying to regain post volume and revenue from banning/blocking Trump.
FB's, Twitter's, and many MSM outlets' suppression and derision of the lab leak theory probably isn't playing well now that they've been proven probably wrong and partisan-motivated.
