(Note: I'm sure they would catch this and it would either be a policy violation that gets you shut down or they would just know how to bill you for it)
It gives you sudo access so you can install anything. Although you don't need root to "install" Terraform, you can just download the binary and run it from ${HOME} or wherever.
LOL, or run a remote VSCode session on it :D (I know that's not gonna happen, but would be kinda cool nonetheless)
