A lot of jobs ask you for social media contacts. They also advertise via LinkedIn and Indeed, which require personal data. So you don’t have to be, but you’ll be lucky if you get one. And, like I said, once you get one, the company could easily just sell the data you give them. Are you going to refuse to give them your information too? Why would they hire you? Why would they keep you?
This is the same “everyone can do what I did” nonsense I get from rich libertarians.
