I'm not sure I see how having a great work environment and culture and compensation package justifies helping a company perform its primary function, if that primary function is harmful. I'm not reducing companies like Facebook and Google to their data and ad practices, those practices are their core business model. It's literally why they exist, despite what they may say. GM makes cars, Facebook and Google collect personal information to better sell ads. The awesome benefits and coworkers and cool problems and neat tech don't change why those companies exist. I'm simply questioning why people still work there, assuming they know what they're helping build. Ad tech. That no one wants or needs.
