Beside mentions of Jetbrains license model, I would like to mention the license model of a note taking app called Agenda[1].
It has a subscription wherein the customer retains the software and all of its functionality even after the subscription expires. One may resume the subscription down the line if they see a new feature worth having.
The creators of the app liken it to a magazine subscription wherein the customer retains the magazines even after the subscription lapses.
From my own experience of using it, I purchased the license for a year back in 2021 and let it lapse as I did not find the any of the new features to be worthwhile. I still keep an eye on their updates as it is my daily driver.
