The rest of your comment stems from that one sentence which is an unfounded assertion built upon an unstated assumption. If you really believe that then this conversation is irrelevant because the platforms are, generally, private commercial enterprises that should modify their terms and delete your accounts as necessary to increase their revenue while you have given up even imagining alternatives.
If you are only a marketing person completely void with any technical competence then you absolutely need platforms to tell you what your priorities are, otherwise you can always self host.
