They don't have need for "cost centers" such as customer support, moderation teams, etc. Facebook doesn't even have a large enough support team for advertisers let alone anyone else that might have some real issues with their accounts, which I think should probably be illegal. You can't offer a service and then not respond to your customers issues/problems, especially if they pay for it.

There definitely needs to be more regulation in tech regarding this aspect. These companies have all the money they need to solve some of these issues, and then some. They'd rather keep that money for themselves and try to enter completely different markets so they can become an even bigger monopoly instead, though (which is yet another good reason to put restrictions on this stuff, because the goal should be to minimize the number of monopolies).
