I did that with Affinity software which was purchased by Canva. Currently they don't have a subscription but I give it a year or two and they'll either have subscriptions or it gets folded into the Canva subscription.
Even if they do that (they explicitly said they won’t), that doesn’t stop us (I also have Affinity apps) from indefinitely continuing to use the versions we already have. So buying non-subscription software was provably the better choice.
Software does not exist in isolation. I am acquainted with a number of people and organisations who deliberately keep otherwise obsolete equipment running obsolete operating systems in order to indefinitely continue using old software instead of paying for new versions and/or switching to a subscription model.
While it is certainly a choice, and one people demonstrably make, it comes with downsides and tradeoffs - it is not unambiguously better.
I don’t think you did it on purpose, but that’s a straw man. Most software that works on one version of an operating system doesn’t break on the next, and they’re not released that often anyway.
And if you really need it, you’d be fine not upgrading until you find an alternative. Which with non-subscription software you can do at your own leisure. That’s my point.
