I think the biggest outcry was with Metal Gear Solid - they had made it so that the game had to be able to contact EA, or it wouldn't launch, and they re-authenticated the game every update... some other stuff I can't remember... but the most egregious was that the game was
limited to 3 installs. And guess what? If you upgraded your hardware, it burned up an install.
There was the story of the guy who had problems with performance in MGS4, so he upgraded his video card, and his motherboard/CPU, and... something else, probably RAM - and suddenly it wouldn't play anymore, saying he'd burned his 3 installs and had to
purchase the game again. EA Tech Support eventually reversed this and allowed him to play more, but his tale achieved Internet Fame status, and EA got a huge backlash of hate mail, boycotts and other crap.
Ditto for the new game, Spore - 3 installs. And a bunch of other crap that I can't remember at the moment. (It's not that they weren't big issues, it's just that all the articles I'm finding online now are the ones where EA reduced its DRM protection.)
A ton of gamers decided not to buy Spore - which has been Will Wright's brainchild in the making since around Sim City 2000 came out (so a VERY long time) - because of EA's involvement. Check out how
Amazon reviewers bashed Spore for having EA's grubby paws on it. It doesn't get much worse than that.
As it happens, I'm actually involved in the boycott on EA. Not as part of some organization - I just refuse to buy EA Games products while this oppression of gamers' rights continues. I'm all for protecting the chance for companies to make money. The programmers have to eat too, you know. However, treating paying customers like criminals is horrific.
Not to mention, they're using SecuROM - known for security holes and spyware - as their protection methods. SecuROM, by the way, which was
hacked and cracked by the Reloaded! team for Spore
before it was even released in North America. Now
that is pathetic.
EDIT: Forgot to mention: After all this public outcry EA reduced the grip of DRM on Spore - but now, if you discuss DRM on the EA forums...
you get banned from the forums, and your account for Spore/MGS/whatever gets removed, and you have to buy the game again. Nice.
