The ability to change features, prices, and availability of things you've already paid for is a powerful temptation to corporations.
Inkjet printers were always a sleazy business, but once these printers got directly connected to the internet, companies like HP started pushing out "security updates" that modified your printer to make it reject the third-party ink you'd paid for:

Now, this scam wouldn't work if you could just put things back the way they were before the "update," which is where the DRM comes in.
A thicket of IP laws make reverse-engineering DRM-encumbered products into a felony.
Combine always-on network access with indiscriminate criminalization of user modification, and the enshittification will follow, as surely as night follows day.
