I've tried twice to make it clear that I'm talking about the wider societal issue of the growing importance of these platforms in public discourse combined with their moderation policies (and the arbitrariness of those policies — since they can change at any time without notice). Since each of your replies ignores this and focuses on individual issues — unrelated to my comment and uninteresting to me — like which platform(s) a person chooses to use, whether Twitter has the right to moderate, or whether they have historically used their arbitrary moderation power in a way that you find acceptable, I'm going to disengage from this thread at this point since I don't think we can enlighten each other in any meaningful way.
