For example, it could be the case than in a given country, a news article in which the son of a prominent CEO does something socially embarrassing relative to that culture (perhaps he didn't get into a top university and instead attends a community college) which causes enough public outcry that he resigns. Is it right for Twitter, Facebook, etc. to push up comments and reactions, via machine learning algorithms or whatever, that bias more towards western (read: American) values about what is considered social outrage?
Conversely, what if ideas about corruption are treated differently in different countries. If it is the case that it is socially expected/accepted to pay officials for certain services, is it right for a western tech company to promote comments/content that show dissent and value western values over the local ones?
