In most engineer discussion contexts, the second the topic of how obviously evil, manipulative, and socially destructive the social, gig, and ad companies that pay well comes up, the people who work or worked for them or aspire to make Facebook/Google/Uber/... comp packages will go to great lengths to defend them. It is really incredible how transparent it is.
"Hey, there are crack dealers, people selling cigarettes, etc. Why are you singling out Facebook?"
It's almost like they know the issue, but think that somehow the existence of even worse scumbags provides them with ethics aircover.
