This is the same logic as organized crime using violence. It’s part of their core business, and if they scale down on violence, other organization will have a leg up on them anf they lose revenue.

We don’t accept mafia escalating violence for profit. I’m OK with facebook (the biggest SNS) losing business because they can’t abuse the system enough.

What about the others ? same can be applied to them, and it doesn’t need to be done in order (no need to wait to regulate Google or twitter to touch facebook)
