Absolutely it is a license to do whatever you want, simply because they don't offer refunds.
My particular gripe: Fallout 3 for Playstation 3. I purchased the game, had great fun. Purchased all the expansion packs and 1 of them just doesn't work (system locks up within 20 minutes max) and the other I can't get into at all (system locks up trying to enter it).
Search the forums for these issues and they are well known bugs. That is unacceptable. I bought two products and can't use them at all. It's almost as if nobody even play-tested the DLC for PS3.
Can I return the defective product? Absolutely not. So I pirated the game for PC because it works better. Will I purchase DLC again? Probably not until I've play-tested it.
There's an old saying in Tennessee — I know it's in Texas, probably in Tennessee — that says, fool me once, shame on... shame on you. Fool me..... You can't get fooled again.
