Respectfully disagree.
Zuckerberg cornered the market on the ability to track every movement of individuals - whether or not they're Fascistbook users.
It is NEARLY IMPOSSIBLE to not be tracked by Fascistbook, whether or not one has an "account" there.
Fascistbook can track all your activity across all your devices without you even knowing about it. That's Mark Zuckerberg's doing.
Jack Dorsey couldn't do that. His "contribution" to the centralization of the Internet was Twatter. Which BTW sends its data to Zuckerberg for correlation, associating and fingerprinting Twatter and Fascistbook users together.
Zuckerberg is clever. And evil.
Dorsey is just evil.
All that is true but somehow Zuckerberg finds himself personally utterly despised by a hundred million Americans.
