Hate them all you want but they put out games with polish that isn't matched by ANYONE in the industry.
Valve would like a few words with you...
Blizzard has launched a few games with critical faults since being swallowed by Activision (just like the popular companies swallowed by EA), the communities have been the ones to quickly fix the games weeks and even months before the developers did.
Some of the best things about WoW were provided by the community, and only months later (if ever) implimented into the game for everyone. Granted, the only thing I enjoyed about WoW was the customizable UI and the community add-ons so I could be throwing a bit of bias in.
SCII was frying equipment because of a very simple ommision in the code line, there's been lots of problems with battle.net (though it's loads better than MW:2s matchmaking ever was)... Ask the Korean gaming federation (or whatever the one that more or less took over the country with SC tournaments) what they think of SCII and it's Asia only pay to play in tourneys mode or lack of LAN.
What Blizzard has, is amazing marketing and a fantastic PR department. I truly believe they want to be a good company like they were pre-merger, but it's not going to happen while they are even loosely associated with Activision. The same goes for SE and most other companies, the money people pull the strings and even the strongest Dev has to throw their hands up in the air sometimes and release something they aren't proud of.
