The publisher you despise the most.

I wouldn't say I despise any publisher, but from the ones I dislike the most, you pretty much nailed it. Recently I would say Capcom, but EA has been outdoing themselves last year, with all the fiascos and shitty decisions, so yeah they are in front now.
Activision made their share of stupid things, and I don't like their philosophy towards games and franchises, but I wouldn't put them in the same league as Capcom and EA.
