I'm not really sure where "trust" enters the equation. Either use it or don't it's not like you're buying life insurance.

Use whatever platforms you want on the merits of what those platforms offer you. Let's stop with all this "OMG so based" or "screw this alt tech platform because ___." They are all jockeying for position to be the main competitor to Twatter. In reality we need to support all of twitters competitors if our goal is to hurt their brand or at least have healthy alternatives.
