Twitter, Facebook et al. have been getting a lot of flak recently for having algorithms that lead to radicalization of users (i.e. maximizing engagement/controversy for ad revenue). I think Trump is the best scapegoat they have for the alt-right radicalization phenomenon, rather than the platform themselves. The events that transpired recently are a perfect distraction for a deeper problem that lies with Big Tech.

(Similarly... I don't support Trump either, etc. etc.)
