If we can limit the issue to Always Online DRM then we can craft an argument which suggests that AODRM is detrimental to the future of gaming. If said argument can be supported, then we can begin to worry about if it's 'moral' (I'm not so sure that's the right word to use, but if we don't get in a twist about specific meanings for it we can simply apply it generally) to oppose AODRM and to what extent one should champion the cause.
And no, of course the future of gaming is utterly irrelevant in the grand scheme of things, but for those of us who enjoy it as a hobby (to say nothing of those who actually enjoy it as a profession) it is at least as important as any other aspect of how one enjoys their free time.
For example, there are many people who love the outdoors, hiking, camping, sailing, ... now imagine that national parks/recreational areas began to require you to wear a tracking device (oh, and also to pay for the privilege of said device) on your ankle at all times you are in the park. Would people rant and scream about this? Would various civil liberty groups make a stink about it? Would you simple accept it as the price of enjoying your recreational time?
Sure, you can poke holes in the analogy if you want to, but it's the thought that counts
