I wish more people understood this and would actually refuse to purchase.
"Consumers can vote with our dollars. Consumer backlash has already affected the rollout of some subscription schemes. Refuse to purchase these products, and join with others who are rejecting these developments."
That does not apply to products which are (essentially) a fixed-feature product. Like most productivity software, single-player games & so on. Tying subscription fees to those should indeed be met with a firm "NO!".
And no, bugfixes don't count as ongoing service (imho). That's more like repair under warranty: fixing issues that shouldn't have been there in the 1st place.
Or the many FPS games, basically all of them, that now require online servers ran by the company rather than letting users run their own the way all fps games used to. (and a dishonorable mention to the subset of CoD games that let you 'run your own server' but only by paying them to spin up another game server in their existing data centers)
