Yes, most people do not realize there is a problem. You have to use a different OS (Mac OS in my case) to discover how nice a working clipboard can be and to feel the pain when going back to Linux.
If anything I find OS X more annoying, as things like screenshots into the clipboard work far less reliably.
Used Mac for almost three years.
Was enthusiastic when I got one and after close to three years enthusiastic to get back to Linux or even Windows.
I realize Mac users experience it to be much better and I guess with a different workflow it is.
I tried hard to pick it up. I failed miserably.
Going back was a relief for me.
It's not macOS' problem if people seem to prefer writing mediocre cross-platform apps than proper, native apps with full support for macOS-specific features like system-wide automation, proper integration with the system pasteboard, Quick Look, accessibility features, etc.
Or is this the projector problem again: when you plug a mac into a projector and it doesn't work, people blame the projector. When you plug a linux machine in, people blame linux.
I'd never heard of the projector problem, but given Linux's unreliable track record with multiple monitors, I'm not surprised people blame Linux. The problem as stated doesn't define whether or not the projector is actually at fault or not, so we can only really start diagnosis where intuition leads us.
