Nobody makes enough money to pay multiple-six-figures developer salaries without people being exploited somewhere, and any $bigcorp is generally incapable of acting in a way that doesn't maximize shareholder value (except as needed to comply with laws). If you want to quit $bigcorp in protest, $bigcorp2 across the street has its own ethical problems.
There is a lot of important software work to be done for the world that doesn't enable mass surveillance, doesn't exploit addictive behavior, and doesn't degrade worker protections or evade taxes. It also doesn't pay multiple-six-figures. You'll just have to live like all of your non-tech friends.
