It's more like "Your purchased game is no longer yours to play, because we said so". Meh. If buying isn't owning, then piracy isn't stealing. And in the old days, DRM might prevent you from playing a legitimate copy because of some hardware issue, the game's copy protection might make you jump through al manner of hoops before it would even start, maybe you lost the required dongle, or whatever. Good reasons to pirate, because it would give you a far better experience. Games have gotten a lot better, but this move sounds like a step in the wrong direction, even if it is more about online cheating than piracy.
Same shit with DVDs and Blu-rays. No format shifting, ads that can't be skipped, random HDCP errors that force me to keep power cycling all devices in my media chain until it somehow starts working again. Here too, the pirated product is better. It's not that I don't want to pay for stuff, I'd love to pay in order to have companies make more enjoyable content. But as a paying customer I don't want to be treated worse than the pirates!
And it's becoming a matter of principle as well. Morally I used to feel compelled to pay, perhaps buying a Blu-ray and only then getting a pirated file (or ripping the disc when possible). But these days? Game companies still have my sympathy, but movie companies have perverted the social contract of Copyright so far beyond its original intent, that I do not feel a single shred of obligation anymore to keep my end of it.
