Other than being a great editor, Vim has great value as a sort of practical joke you can play on people new to the command line.
"You can't figure out how to get out of the editor? I'm busy, stop asking me stupid questions. Look for the answer on Stack Overflow. Make sure to leave your mark there by up-voting the answer."
Yes, I hate people that can't read, too. Vim fucking tells you how to quit as soon as you hit ctrl^c. What the fuck m8. It's not even a funny joke anymore. It's just pure cringe.

Type :qa! and press <Enter> to abandon all changes and exit Vim
Maybe not quite what the user was looking for. But I guess it does get you out of Vim.
ETA: Also, that answer on Stack Overflow at one time was the answer with the most traffic on the site. Reading must be a common problem for trapped Vim users.
I think abandon-changes is probably the best suggestion for most people in that situation. If you don't know how to exit you've probably made some accidental changes.
