Nationalize FAANG?
If one wants to subject these corporations to regulations, than it seems one should propose regulations. Putting them under the direct purview of a government does not magically make them start working in the best interest of the people (of which nation?). Nor does it mean that they are automatically accountable; see for example the NSA if you want examples predating the current administration.
Feeling a big "NOPE" on that one.
Customers need to make it unacceptable for FAANG to act this way... Good luck on that tho.
Unfortunately, they have been very good at slowly raising the temperature so the frog (read:us) doesn't jump out of the pot.
