As for the core of your point, frankly, half of the Silicon Valley would be jobless. Not just Uber programmers who already proved who they are by developing Greyball. The whole business of Facebook and Google is centered around tracking people. Amazon will happily accept fake reviews and products as long as customers pay they're happy. Netflix officially says they're competing with the time their customers use for sleeping. Apple will do everything to make their products environment unfriendly, unupgradeable, with ton of additional accessories produced only to increase their profit. So really, I understand your idealism, but the ship has already sailed and you can call yourself lucky if you can work on a product and for a company that are 100% ethical.
