You're correct, I signed a contract that says they own my free time. I didn't exactly want to, and I firmly believe it's wrong. Nevertheless, it's easy to say I fucked up when you don't know my exact situation. This is my first job and there are a lot of other benefits that made it the best option for me personally, even when there were alternatives that had no such clause.
That's fair, I don't know your situation, and my tone was overboard. I don't mean it as a criticism of your actions as much as a warning for others not to do the same without good reason.
Does that mean if you do something semi-illegal or immoral on your freetime they put their name on it? Start doing work on decrypting media (legal if the content is out of copyright, but good luck finding such a thing), porn (again, legal but many won't like it and you can find weird stuff that is even less liked while still legal), or something else that might technically be legal but they don't want their name associated with.
If your company owns your free time as well, you've fucked up and should talk to HR.
