I can get whatever TV show or movie for free online but use my DVR for TV and Netflix for movies. They can keep my DVR and I'll cancel the Netflix account and just download whatever movie I want rather than give either one of them any money. Of course using the cable companies bandwidth to download them.
Actually I think the DRM and game devs are separate beasts.
Someone like Maxis develops a game (Spore for example). Securom is the one doing the DRM. Sure Maxis needs to implement it in the game but the DRM is written and sold by Securom, probably at the request of the publisher.
I wouldn't call Securom game developers is all I'm saying but as I said in my other post, if they were included in interviews, I'm sure they contribute to the numbers that say DRM works. :)
It's kind of the same structure as music in terms of the publishers (labels) and developers (artists).
It could also depend on who they talked to in terms of developers. I'm sure if they're interviewing some of the higher level developers/leads or the people who have a job because of something like DRM, you'll probably find the middle ground between the average developer and the publisher... Like the 50% that seems to think DRM works.
The average game developer isn't far off from most gamers. They buy and play other companies games and see the same kinds of things we do.
