Your IP contracts contention is pretty much hogwash. It's FUD trying to scare people when 99.99% of people aren't affected by it.
I know plenty of developers who worked part-time on their startup at well-known SV companies. Two different sets of coworkers subsequently quit, and each sold their company for ~500M. Another one has gotten several rounds of funding. Another one sold their company to an enterprise company for over $1B, and after the earnout period was over, they formed a new company.
There was nothing "onerous" about any of the contracts these people signed. Meanwhile I haven't heard the opposite at all.
