Look im an IT guy, and enforcing 2FA for all accounts at our company directly caused at least 2 people to quit at my company.

People are enormously resistant to change. It doesn't even matter if it actually impacts their job or anything, they will freak out and complain.

Hell 2 weeks ago I added a 3rd AP to one of our offices and just the act of moving the APs around caused enough of a disturbance that HR heard about it. And that was me giving them better internet! There wasn't even any downtime! I just moved the things that sit on the ceiling and nobody notices!
