I came to the conclusion early on that that is the nature of capitalist work generally, so pick your poison. I don't agree with the whole system, but also don't think this employer is worse than most others on that front. It's just formulated in a legal clause where other employers might just litigate later if they needed to.

I get paid well, and have never had a problem -- or seen others have problems -- open sourcing things where it made sense; including things that I worked on at work during work hours such as abandoned/cancelled projects or things that made sense for the community to have access to.

EDIT: also your tone sucks, this is HN not reddit.
