Friends of mine who play one of the Blizzard games (World of Warcraft) and work at a (non-MMO, console based) game company don't understand that everyone else views gaming, especially PC gaming, as a non-legitimate hobby and a questionable mark against you on a job search, funding search, or anything of the sort really.
It's not like religion, race, political affiliation. It's a very legitimate concern, as there is a tendency for people who play these games to stay up much of the night instead of getting a proper nights rest. They don't understand how much they're giving up people's privacy; lots of users will stop playing these games for professional reasons. The bank vice president: Gone. The guy running a business: Gone. The advertising exec: Gone. None of them can afford to have this come out professionally.
