I think I'd happily describe the multiple clipboard situation in Linux as a dumpster fire...

It's awkwardly 'solved' by clipboard managers merging clipboards but it's still wonky. Even for somebody who has been using Linux as a desktop for many years I occasionally find myself annoyed by it.

At this point I think I'd prefer "copy" to be an affirmative action rather than something that is done automatically. It makes pasting over existing text much easier.
