Well, I'm not going to answer you Shamus, just ask yet more questions!
I am playing a game, the DLC/add on/whatever is there, I've had to download it onto my hard drive because the game won't let me play it without the latest version.
So my hard drive contains vast amounts of conent that should be playable, it's there, it's installed. But I am not allowed to touch it due arbitrary imposed constraints.
Does that mean the developer should pay me when it comes to replace my hard disk because of all the crap they've put on it for me?
Since they've already put it on there, is there any moral/ethical reason I shouldn't just hack the game until I can use it?
Hunting down illicit downloads is one thing, but is it reasonable for a dev to forcibly* install content on my machine and then not let me use it? If I buy a DVD and it won't play I either take it back or start look at work arounds until it does, surely this is no different?
What about discs with content already on them that has to be unlocked? Resident Evil 5's minor infamy for the multiplayer 'download' sticks out in my mind. Would it be unethical to just copy the UI/front end for multiplayer from somewhere and patch it in myself rather than paying for it? It's on the disc, I paid for the disc, the law says I own it regardless of what the EULA might tell me.
Downloaded and online content seems like a massive moral/legal grey void to me. More specifically a void with no botom and no guard rail to stop customers falling in.
The ever increasing amounts of paid DLC and heavy DRM is going to hurt us as players (even more than it does now). I don't particularly fancy the idea of resorting to piracy to actually be able to play/back up/modify/enjoy games, but it is increasingly looking like the future.
*whilst not literally forced game updates are still a Hobson's choice, you can either take the update and all that implies, or junk the game you just spent $60 on.
