I know I've seen it a couple times, but can't find the search terms to find them now; jetbrains model is a bit wonkier though (key term: perpetual fallback license) -- you subscribe annually, and if you stop the subscription, you roll back to the version available at the time you last paid. So you're basically buying the software as it is today, and then getting a 12-month trial of the updates happening from there.

This doesn't seem to be any better incentive-wise than the model I described (stopping payment stop further updates, so you keep whatever you have today), but comes with the user-backlash of losing what they thought they had (no one feels good about rolling back)
