You can't be fired from Linux, and if you contribute to the codebase, you do own it under the terms of the GPLv2. (Idk if Linux does copyright assignment but even if they do, it's still GPL).
Whereas a company can tell you to fuck off for literally no reason, give you nothing, and shove you out onto the street with no healthcare and no salary, and then sue you if you if you try to do anything about it.
