These companies investors should be stripped of their assets, and the fora made public services--without surveillance, data sales, or the ability of government covert censorship. Investors should follow ZuckerBorg's lead and divest Fakebook stock quickly, before the law catches up with them.

These companies are on bed with the law and related institutes(NSA, CIA etc.) When law is corrupt, don't expect it to do anything good.

The way I see it is that a business is a private entity. Banning someone from a social media is the equivalent of you evicting someone from your property because you don't like their behavior. They are free to exercise their free speech anywhere outside of your property. My only problem with FB is that they are not fully transparent about what kind of data they collect. Individuals have the right to sell their privacy and dignity for free stuff and as long as the kinds of data collections are public FB, Twatter etc. should be left alone. Let the intellectual Darwinism play out and the idiots will ruin their lives.

I do not have that right in a conference hall I own.

You don't have the right to obstruct free speech. If you do own the conference hall, then they can only be present under your consent which you can revoke (unless you already have a specific contractual obligation) So in most cases you do have that right in a conference hall you own.

Furthermore, Fakebook, Twatter, Goolag and the rest aren't actually private businesses.

This is a a different topic altogether. I'd say they are privately owned and on bed with malicious private entities. A cop in the pocket of a gang is still technically a cop. But that kind of cops should be removed. In the case of Fakebook, Twatter, Goolag etc. they should be shut downed and fined for NAP violations. But banning account is not a NAP violation as users opt-in for the service of a private company that is colluding with a malicious entity.
