My Sublime Text licenses are perpetual. I have various perpetual CAD licenses going back to the 90's. Same for some development tools, some, or maybe just one dating back to the 80's. (MAC/65) MSDOS All versions of Windows I have used and or purchased. Microsoft Office Libre Office SGI IRIX And I could go on for a long time. Point is a whole lot of software runs on some sort of perpetual license. Any why not? It all does what it was written to do. Until very recently, with the rise of software in our browsers, one could expect most software to operate this way. When new versions are needed, AND if needed, payment for that work is obvious and entirely reasonable. And with some software navigating what happens if new is needed becomes huge pressure to get people to upgrade. And that is sometimes unpleasant. CAD is one of those for sure. Subscription software, in many cases --and I am speaking generally here, can be easy to subscribe to. All good right? Well, I tend to keep software that2, Supports my skills. Doing that would be huge payments! As a buyer,I expect to see software coat / licensing make better sense.
