Start where you work. Participate and start discussions around ethics when your company engages in something questionable. You don’t have to threaten your job, but you don’t have to accept as business as usual without any critical thinking. Persuade your colleagues to do the same and lead by example. Or just quit, if you’re working for Facebook. Insanely smart software engineers are not plentiful. If enough people declined to work for Facebook, they will be feeling an impact in their bottom line and scalability.
