This is the fundamental problem of the business of making and distributing art, whether it's TV, movies, music, or games. It's not a commodity, it's not, generally speaking, fungible so it takes a much more principled stand to force change. If you don't like, say, the way a certain bank or grocery store or gas company or what-have-you does business you can just switch to a competing product. Even if that requires compromises generally there will be alternatives which are suitable substitutes. But that's not the case with artistic works. There is only one The Beatles, only one Veronica Mars, only one Citizen Cane, and there's only one SimCity series. You can decide to avoid playing the new version, and you can decide to play some other game, but these are all wholly inadequate substitutes.

And this is how game makers and publishers have managed to get away not only with astoundingly bad DRM but also in releasing quite broken and incomplete games in some cases. It's because gamers continue to let them get away with it.
