2 years ago, it was fashionable to hate on Zuck for X, Y, Z reasons.

But then Elon became the main character in the social media business and the new fashion is hate on Elon and cheer for Zuck.

“Do not trust to the cheering, for those persons would shout as much if you and I were going to be hanged.” —Cromwell

I've noticed that hating Elon, or hating Zuck is one of the more obvious external signals of a person's political ideology.

Answering the question "where's the beef?"

People have a yearning to hate I guess Elon is the new Trump to a lot of people.
