"The Industry Standard"
From TFA: "We've changed how and through whom we will sell our software. And we've completed the software business-model transition that began to accelerate in 2019, from selling perpetual software to subscription licensing only – the industry standard," he added.
I suspect that far more software is sold via perpetual license (pay once and you're done; you might or might not get some free upgrades) than is sold via subscription, although there's a lot more talk and print (in other words, "hype") about software subscriptions.
It's a lot easier to find ten people willing to pay you ten dollars for a software package than it is to find one person willing to pay you a hundred dollars for that same software package. But it's a lot easier to achieve customer lock-in with subscriptions. They may start with a reasonable price, or even a loss-leader price, but after the customer has converted to using that, and their data have been moved to "the cloud", the rate-hikes begin.
Our company had an IBM mainframe, but at some point, our expanding needs and IBM's pricing structure made it cheaper for us to go with Plan B: we got an Amdahl V6 (IBM mainframe work-alike). It was relatively-easy for us to do that, as we had all our data physically on-prem, on our discs, and on our tapes. Had our data been "in the cloud", we would have been boned.
