The problem with all of this is that these allegedly private organisations are no longer acting neutral. We have the government compelling Mark Zuckerberg onto the senate floor to be grilled over Facebook's data use, does that sound like a private company to you? We've crossed the line that separates government from private entities.
It's clear that Facebook, Google and other companies that admittedly have reach and some influence are being controlled by the U.S government, in a sneaky indirect way.
