IMHO, the libertarian trends of thought are pushing people to think everyone as a trader and abolishment of professions. From that perspective, business is business and the employee should have striken a better deal but from a professionals perspective they are not businessmen - they are professionals and the business is handled by someone else and they join a team where they get compensated for their time(they don't expect to get rich in the job, they expect to have stable career until retirement).

When the distinction is not clear, professionals are essentially getting ripped off. If it was clear that everyone is a trader and some trade their coding time, then Meta wouldn't be able to do this because the trader would have put the cancellation terms in the deal. If it was clear that they are professionals and don't with FB but join that company, then it is expected that the law should protect the workers.

It's the worst when you ara positioned as a single person trader who doesn't want to be a trader, doesn't have the skills of a trader and trades with a giant trader.
