We are fortunate enough that even the most mediocre among us can hold out for the next employer that doesn't demand this kind of control over you, or start your own company. I don't give a shit what a company says about their culture of work/life balance or whatever. If I see blanket IP clauses unrelated to non-compete, or like arbitration clauses that remove us from civil courts should a problem arise, I'm whistling on my way out the door.
I once saw a contract that stated I couldn't work in the field for TWO YEARS after terminating. Not just large machine equipment, but ANY mobile/web applications, related to integration with embedded systems or not. Yeah no thanks.
Your mind should be available for rent for $100k/year or whatever your market rate is these days but not for sale at that price. Sorry but I'm a Human as a Service. If you want to own me, you'll have to come to a better valuation.
