Blatantly false. They aren't liable as long as they promptly action reports, just like everyone else.

My impression is that they don't like the bad PR currently associated with various debates surrounding use of social media by children. At the same time they don't want to implement various policies that would be popular with the general public but would hurt their bottom line (ie they don't want to do the right thing).

So instead they make a big deal about various imperfections to justify draconian solutions that would see them able to implement all sorts of privacy violating measures. Thankfully that failed so now they're engaging in a smear campaign.

The current conduct of these companies in this regard is openly evil.
