There are a few pieces of software I use (regularly) that would continue to get money from me if they followed the old model of paying for major versions. (pay for v1, get v 1.1-1.9) with v2 being the next “big” update that you’d have to pay an upgrade fee (smaller than a new purchase) to continue on the train.

But they switched to subscription model, and lost me as an “active” customer.

YNAB is the big one I use at least weekly, sometimes daily. I am on YNAB4 until it will no longer function because I’m not paying them a monthly fee to use that product. I would have GLADLY paid for major updates/changes even if it equaled the subscription in the end. But each of those purchases would be a decision I made on whether the change had enough value for me.

Subscriptions all them to not strive for large enough improvements to warrant a version update / upgrade fee. They just run along with little or not useful changes (IMHO).
