It’s not clear, yes: I think they have way too much power in the wrong hands. Now, hypothetically speaking: If they were to lose most of their users, they would lose their power. So, in one way or another, everyone supporting those platforms (by using them) is part of the problem - and that would be the reason to stop using them (again, I know this is quite hypothetically).
Yes but again, this is about stopping to USE them. Deleting your account versus not using your account at all doesn't have any difference of outcome here.
