This is so frustratingly common. I worked for a company I loved and it got bought out by a company I hated. When people (including me) started quitting, the CTO said “but why? We have video games in the break room.”
Large companies are often run by crazy people, I guess.
I’m OK with prohibited public burnings for the purpose of fire safety, I guess. Beyond that, I don’t think I’d want to limit free speech in this manner.
