There have been occasional examples of misbehavior and ignoring the license terms of certain FOSS licenses, but by and large almost everyone -- including corporations -- does abide by them. The common licenses are well-written, legally solid, and most lawyers (again, and most importantly, including corporate lawyers) agree they would be enforceable in court.
I don't know if you've had a bad experience with releasing free / open source software, and I'm sorry if you have. Many people have seen good results from doing it, and furthermore there's a baseline level of digital freedom now available that is entirely due to people producing such software. The most obvious example, of course, is that you can run a free operating system on your computer and thus not be at the mercy of gigantic tech companies when it comes to privacy, advertising nuisance, non-configurable user interfaces, etc.
