The argument "you will find yourself on the other side" is weak. First, it's just a threat in disguise. Second, it's a weak threat because it's hard to realistically imagine Besos or Cook trying to start another Parler.

What's happening is just morally wrong. Not because the situation may flip, but because there's a higher moral law to things and what's happening contradicts this law. Even if your side appears to be winning, it's actually losing, because it's losing its soul.
