So, really, it's Microsoft that decided "we're different".
Also, as somebody who sort of lives in the terminal, the lack of the Command/Ctrl distinction is one of the things that really bothers me about Windows. In default GUI applications, application shortcuts use Command, and Ctrl is used almost exclusively for headline-style shortcuts (ctrl-k for kill line, ctrl-a for home, ctrl-e for end, etc). Ctrl-a Ctrl-shift-e is kind of baked into my brain as "select whole line".
