JetBrains ran aground of this years ago when they introduced a subscription model for their (excellent) software. People (rightly) lost their fricking minds when they heard that if they cancelled their subscription, they'd lose the ability to continue using the software they'd already paid for.
So JetBrains went back and reworked their system so that a cancelled subscription would continue to have the rights to install all the software that existed up to the day of cancellation. Effectively meaning that if v3 came out the day before you cancelled, you can still install and use v3 10 years later.
JetBrains comes to mind as one of the fairest subscription services I know. It also get cheaper the longer you’re subscribed, incentivizing you to to stay subscribed. It’s both smart and user friendly.
The worst one is probably Adobe.
Duolingo. Why can't I just pay $100 or whatever one time? Languages don't change to the extent that it needs to be a subscription.
There really should be a free and open source alternative for Duolingo. I know that there is Librelingo, but that is currently only doing Spanish for English speakers.
