The question is not that it has always been that way. The question is that different systems do things differently and one must take time to learn it.
If I would use an Apple system I’d have to learn how things are done on it. Of course you can always compare different approaches, but take time to understand why the differences exist.
When I use Windows I often miss the middle click copy, but I’m not saying window copy paste is broken for the lack of it.
Again, sorry for being harsh. A vacation is very much overdue for me.
