It would require modification to copyright law in certain aspects (requiring “pass-through licensing” so to speak) and there’s utterly no will to tackle this in the US.

But those sorts of issues are already problematic for, eg, music licensing for games/shows/etc. Some of these types of hyper-limited, time-gated, non-product-ownership-following licensing agreements need to just be outlawed as unconscionable when they’re gating hardware that ends up in landfills or cutting off the public’s access to cultural touchstones. Or just shorten copyright significantly in general.

“What can you possibly be complaining about!? It was secure when we released it! Maybe you should just buy a new one with less vulnerabilities!”

EU isn’t wrong that people have an intuitive sense that appliances like printers should have a worthwhile lifecycle and for some classes of devices this lifecycle should be quite long. 10 years really isn’t unreasonable.

Also, just like everyone has to support usb-c charging regardless of whatever other proprietary alternative they design… vendors should have to support a couple generic standards (postscript/Ghostscript and CUPS) that relieve a lot of the ongoing maintenance. There are very few/no valid reasons you couldn’t implement cups/postscript if you really want.
