I like DLC. I'll say it. Sure, some of the costs I quibble with - small packages for too much mostly, until they finally wise up and bundle em up - but overall I enjoy DLC for the games I play. Then again I play mostly RPGs and the DLC for them basically falls into two categories: 1) additional quests +/- areas and 2) pretty up your party. Both of which I enjoy personally, though I am absolutely more willing to pay for expanded play than I am visuals and feel pricing should reflect the clear difference in content type. Oblivion, Skyrim, Dragon Age Origins, Dragon Age II, Fallout 3, Fallout New Vegas, Mass Effect 1, 2, and 3, etc. have all had DLC I have felt perfectly comfortable paying for and enjoying for a number of years of replay - based on the original game as much as the DLC that now compliments it and expands it in my replays.
I suppose that for other genres might be different in terms of types of DLC and therefore the perspectives players take on purchasing them. Granted, not even everyone who is mostly concerned with RPG DLC would be on the same page on all items all the time anyway. I could easily see, though, from some purchases my fiancé rejects making on games he likes - FPS and Turn and Non-Turned based strategy games primarily - where the type of content and what it adds to the game is different across genres.
Half my list up in the first paragraph is from EA/Bioware though so? I don't think this person is way out of line saying that DLC can be desirable for both parties. I do think he overgeneralized and is probably going to take some heat for that because the world is a reactionary place. If he's talking about the games I've been playing that his company has been making, then I'd have to say I agree with the sentiment in part at least. If he's talking about all games of all types everywhere, then he's not really thinking his statements through, or is a moron, one of the two.
