I’m not sure of you are trying to be funny, but just in case you are not, if their only working environment was a terminal and they didn’t know how to get out of vim, they were fucked to begin with.

I’m guessing they entered vim because they copied it from somewhere, be it another window, having vim in a terminal emulator, a mobile phone where they searched whatever, or another PC. If we are talking about a non graphical PC with just a single tty or a user without the knowledge of changing ttys or without the knowledge of searching the web from the command line, who somehow entered vim without external input, that’s kinda on them, idk. There’s several fuckup steps in there, all nicely stacked.
