If I was happy with the subscription model, I certainly wouldn't be wasting my time online defending it. Unless Adobe was paying me to do so.
If I got what I wanted, I would be happily be going on with my life. You can't expect change if you don't speak up. If I was happy with something, I would save my breath for things I was unhappy with.
I'm getting along just fine with LR and CS6 for now. They do everything I need, and then some... But I fully plan to have to move on when I get my next new camera, and have no ACR support for it unless I start paying monthly extortion for more than I need, to get what I need. I would pay for ACR updates, but I positively will not pay $10 per month just to get raw support for a new camera.
I personally believe that Adobe has realized that they cannot come up with enough compelling new features (other than bells and whistles) to add to future versions of Photoshop, to justify people paying big bucks for those future upgrades. They've hit the end of the gravy train, and they needed a scheme to provide a revenue stream in the future. They can't maintain the revenue they're used to just by selling ACR updates.
I have some great cameras that are serving me well. But when the next version of one of them becomes available, it's goodbye Adobe, because I won't have ACR for that camera. So I'm carefully researching my options, so I will be ready when that time comes.
I'll bet Adobe is counting on the subscription holdouts knuckling under when they get new cameras and need raw support. They can count me out.
