They are free to make any choices they want, and in return I'm free to stop buying from them.
It's pretty safe to assume that any good game will be cracked whatever they do. They might manage to make it so that only one twisted genius can figure it out - but one is all it takes. Once the crack is on bit torrent every one else only needs moderate intelligence to use it.
At that point the free version is superior to the version you can buy, not just because of the price but because you don't have to deal with the DRM system. Not a good way to encourage people to pay up. I'm generally against piracy but I have sympathy with people who just want their game to work without the CD or when they are away from the internet for a while.
Mind you I was never likely to buy their game in the first place - the last game I played was NWN and I only bought that because I wanted to support Linux game developers.
