However this is trivially fixed because in Emacs everything is configurable. Keymappings are very easy to change (I'm using my own, completely custom ones, in my own keymapping minor-mode). There's also the "evil mode" reproducing the very superior (compared to Emacs) vim keybindings. So it's not true that they cannot be fixed. Not only can keybindings be fixed but a) they should and b) it's trivial to do so.
I'm using my own minor-mode which contains all my keymappings. Doing it that way you'll hardly ever have conflicting shortcuts.
evil-mode is an option too for people who want the (way better) vi(m) keybindings.
