It's 21st Century Microsoft. You don't own anything by buying into their services. Not even a perpetual license. It's not like you get a nice manual or shiny product box anymore. That ancient copy of MS Works 3 still works (well, maybe not the original media). Office 2007? Not so much.
Not a unique phenomenon of course. This is basically true in all manner of retail.
Perhaps the best seller for MS is where they offer bundles to corporations with a ton of functionality in, that doesn't make it onto users desktops. For example, I'm aware that we have PowerBI licenses for several thousand personnel but due to the way the IT is being mangled, barely 100 users have access to it. Now that's a profitable arrangement if there ever was one. No doubt the licensing is bundled; making it "impractical" to unpick it and pay for what you actually use.
Quark went even more aggressive, making physical media "un-resellable". Try using that license key from a copy bought off ebay, and you'll be greeted with Quark sales offering you a subscription.
Is that so different to vermin media and their "bundles" with a tonne of stuff that nobody wants, but can't unpick? Landline phone? 20th century target for spam calls. Subscription Film channels? Don't care! The UHD channel(s) recently added? Similarly, don't care.
In a rather more extreme case; there is a type of instrumentation that I work on. The hardware is still fully functional, however, the software is classed as "obsolete" in the eyes of the retailer. If you want to log a support ticket, they will insist on the hardware being replaced (to the tune of $250k). Needless to say, this supplier has basically been blacklisted and we use others instead.
I don't mind paying developers for quality work, but the instant there is some sort of sub tie in, sorry, I'm out.
