No, it looks good on your resume. The type of clown who would get upset at you working for Facebook is not someone you want to work for anyway so consider that another plus.

Some people get extremely sanctimonious about the latest thing their politics or corporate "news" media or the current popular trend on twitter gets them riled up about. Of course they will never face up to the fact that the companies they work for and buy from are neck deep in politics, consumerism, advertising, influencing, the war industry, corruption, greed, etc., too.

These people aren't nearly so brave or numerous in the real world as they would have you believe though. If you personally feel okay working for a company then I wouldn't bother worrying about the opinion of hypocrites.
