I had the same thing. It was an otherwise very interesting short term contract that I really wanted to do. I had a spare time project that I was already working on though. I ended up taking it and pausing my side project until the contract finished. One of the more ridiculous things it said was something like ‘no inspiration you have during the contract validity may be monetized’.

That’s what finally convinced me to release it later as Copyleft, not because I thought they would come after me but because patent law can get fecked.

I also met my wife on a gig where we both signed NDAs with non-fraternization clauses.
