Does it matter if they're responsible anymore? We're talking about companies that have become so titanically large and so obscenely rich that there's literally no way to challenge them for any normal person. Not even to mention the extreme level of capture and Corruption of the justice system. Does Jeff Bezos or Mark Zuckerberg or whoever else we're talking about have to worry about anything if at the drop of a hat they can just turn to an Administration that will sabotage any possible retribution?

Assuming those alternatives also aren't either sued into oblivion or just outright blocked at the ISP level.
