Very good list, I have seen most in action. I would also add AI where some people just make their own internal tools rather than making it open source to everyone.
> Apple is the classic example of an employer that simply doesn’t let most staff do outside open source
I have been encountering this a lot recently, and I don’t know why. Last one a couple months ago, a company wanted to hire me for some work and while all verbal promises were good, when the contract was sent, it has some shady terms but workable nonetheless, except one, the company prevent you from working in any open source work, including personal ones without a written permission, and everything you do will be the company property on or off duty! Obviously I challenged that and they got offended to even dare to challenge it, no deal! Other companies too but that was the craziest one so far.
