I wanted to comment on the same statement. At a minimum all those companies share with law enforcement and national security to some extent. Beyond that I've heard of data sharing agreements and some kinds of data sales at more than one of the FAANGs, and can't see why they would stop, though I can definitely see why they might be two-faced about it and try to give that impression.
Yeah but does that matter when they have expanded the walls to encompass pretty much everything that most users do online.
