Yes. That’s the whole point of them: you give away your information and most of your rights. Even if it’s something like Lemmy, open source, free, no ads, etc, you’re still forfeiting your rights. Because otherwise you cannot share anything publicly. Only private and inaccessible platforms can protect your rights. For example, a private Telegram channel protected by a password and with forced E2E encryption might protect your rights (I’m not sure about Telegram ToS, so I’m not 100% sure), but public platforms - never. They’re public, that’s the point.

Yes. Seriously stop giving them free content.
