No it will NEVER happen. The lobbyist would kill it if it started. And it would get killed in court. Somebody would violate their NDA on social media, get fired, sued, and the courts would point out that the law is beyond stupid and entirely unenforceable.
If your behavior get tied to the company and causes the company embarrassment, buh bye. There’s NOTHING new about this concept. The only difference is how much easier it is now to do something stupid and get it tied in public to your company. People should be smart. And your “what ifs” are all strawmen and pointless. Reality is the guy acted like a stupid baby, and it got linked to his employer. He’s a moron, and probably should have been fired just for that.
