Someone else was complaining that they didn’t keep FireWire. Should modern Macs come with ADB ports?
A 20-year old machine that's critical to a factory can run off a serial cable plugged in to an expansion card running software written in the 90's that will still run on Windows 10. Nobody in their right mind would decide to write that same software on a Mac.
If you compare where Apple is and where Microsoft is also, it doesn’t seem like chasing enterprise PC sales was as good of a long term bet as going after the consumer market....

I don't think it's unreasonable that Apple hasn't done so, but neither do I think doing so would be unreasonable. Archive.org can emulate Apple II's in your browser, I'm sure Apple could add an equivalent feature to MacOS if that were something they cared to do. They obviously don't, and that's their prerogative.
