I have a serious issue with subscription software and have none.
SaaS is what got me off of Adobe (wasn't much of a fan of Corel, I had X5 and X6 which was apart of my digitizing software, installed X5, but not X6) when they swapped. I still had Win7 at the time on one bare metal machine for awhile after which it was through a VM. Win 10 is what got me off of
Windows past 7 even in a VM.
Windows itself will eventually be a subscription service even for the regular user. I know some that have done it just to be able to have Enterprise edition that they wouldn't otherwise be able to have. Ironically, I remember when Corel was actually using as a selling point that they still had a perpetual license when Adobe was doing what they were doing, I think it was just 2 short years later, Corel was really pushing their subs over perpetual.
The problem with software that's going on 40+ yrs old, it's hard to innovate. About the only innovation that is going on now is buying out tangentially related software and offering that up. Outside of that, there is little if any innovation going on and as such hard to get people to want to upgrade to the next version at that point.
I imagine at some point, the 2 big OSs (if the third is still around, a lot of things going on with it that's no bueno, but I digress) will probable just have enough software/firmware to bootstrap a server instance on the user's thin client and all of the programs will be installed on some server. Going back to dummy terminals (unfortunately, at least back in the day, everything was still on a local server versus what it's going to be now).
