Actually, on the 'always on', the legitimate players hate it too.. And those of us that have been gaming since the early 80s (hell, the late '70s), we've seen companies come and go, so there's no expectation that they'll still be hosting a game you may just want to play in another 30 or so years (there are still ones that I'll pull out and play after nearly 20 years, just for the nostalgia trip and the fun of rediscovering forgotten stories).
There's network outages, routing problems, straight denial of service attacks (or compromises of the login servers creating mayhem), playing on a train, a plane, or even in a campsite (I actually enjoy camping; gets me to some very strange places, and a laptop is great for the rainy days; usually used for on site photo manipulation of the shots I take out and about).
Online only, for most games, is an artifical single point of failure. It'll mess up a product you paid for with no warning, and possibly irrevocably, all out of your control, with you having absolutely no recourse. That, to me, is an incredibly bad deal. If it's a bad game, then people will be less likely to buy from them again (exacerbated by the online only issues, meaning an even smaller available market, possibly making the difference between surviving as a company and going under). You don't care about the longevity, but you're left with a bad taste.
If it's a great one, then it's not going to be around for the nostalgia trip. When gaming lines are shut down by an active company, then players will be more wary still.
For all the 'big business' groups, thinking that this solves all their piracy woes, they'll be meeting the laws of unintended consequences, where games that don't follow this will have the exposure, thus the following (maybe not immediately, but eventually).. The following generates the sales. The sales bring in the cash, and cash is the lifeblood of a company.
Best analogy of the companies following this route is "Emo". It's very much an "I'll cut myself because I don't like a few people". Not the hard core self harmers who are actually ill, but the ones who'll do it for attention and because they think it'll make them edgy, or gain an advantage, whereas in the long run, it'll likely turn out to be self defeating, pointless and rather embarrassing.
