The Musical Museum in Brentford might take them off your hands. They have a large collection of fully operational and lovingly restored self-playing instruments.
As somebody who recently had to switch to Mac for work, my experience has been the exact opposite of this. Every other OS I've used since Windows 95 I've been able to get to grips with the same way: start off using the mouse to find my way around the UI, and introduce keyboard shortcuts as and when I find them useful. Eventually I get to the point of being able to use either exclusively keyboard or exclusively mouse for most tasks.
MacOS seems to _require_ some unergonomic combination of both from the get go. Some basic things are easy with the keyboard but hard/impossible with the mouse and vice versa. The Finder app doesn't even have a button to go 'up' a directory for god's sake.
It helps to keep in mind where the OS and its core user base is coming from.
For the case of the up button for example, prior to OS X the Finder was a spacial file manager where each folder had a single corresponding window that remembered its position on screen, allowing users to rely on spacial memory to quickly navigate filesystems. Its windows didn’t even have toolbars, because they weren’t navigator windows — every time you opened a folder you got a new window (unless that folder’s window was already open, in which case it was foregrounded).
So when OS X rolls around in ~2000 and switches the Finder to navigator windows, they’re looking at what existing users will find familiar. Back/forward is easy since most had used a web browser by that point and map cleanly to most people’s mental models (“I want to go back”), but up? That’s a lot more rare. A handful of folks who’d used an FTP client might’ve been familiar with the concept, but few outside of that few would’ve, and how “up” relates to a filesystem is not in any way obvious. And so, the Finder never got an up button, just a key shortcut because anybody advanced enough to be hunting down shortcuts is going to understand the notion of “up” in a filesystem.
I think feudalism is a misnomer here. Feudalism is a historiographically messy concept to begin with and many Medievalists reject the term outright. But even if we were to distill it down to some simplistic yet workable definition I still don't think whatever we come up with would be applicable to the present situation without seriously torturing the analogy. 'Rentier capitalism' would be more apt.
I've been throwing around the term "neo-feudalism" and people seem to get the gist of what I mean intuitively (paying dues to the monopolistic ownership class, only now you're working digital land) but your suggestion of "rentier capitalism" does ultimately fit much better.
