That's because you are paid for your time...

I know that sounds callous but it isn't rare at all for high level functionaries to hold positions in more than one entity, the board of directors of OpenAI is an excellent example of that. And some of those are arguably already conflicted.

Worker bees get paid to work, and companies would like to get a certain amount of time for their money because that what it says in your employment contract. You don't necessarily have to agree with that but then you have to carve your own path rather than to hitch your horse to someone else's wagon.
