Bummer. I switched to Affinity (Photo, Designer) this year and am very happy. You can buy a lifetime license across all platforms (iPad, Mac, Windows) for a fixed price. It is great to have high quality software that is not a subscription.
I like new useful functionnalities as anyone but if the licensing model change and I don't like it, I am also content with not having them. The key us to not taste/knowing about them. Ignorance is bliss sometimes.
Great point for Windows. iOS, Mac, and Linux evolve too much to reliably run 10 year old binaries.
We are talking photoshop anyway so it isn't relevant in that case.
