Is it legal? Windows RDP on github actions

Hey I found a repository that lets you host windows machine & access it via VNC or Windows RDP. That machine runs on github actions & ngrok.
I have no idea whether this is legal or not.

GitHub Terms for Additional Products and Features - GitHub Docs

In order to prevent violations of these limitations and abuse of GitHub Actions, GitHub may monitor your use of GitHub Actions. Misuse of GitHub Actions may result in termination of jobs, restrictions in your ability to use GitHub Actions, or the disabling of repositories created to run Actions in a way that violates these Terms.

We might need to get into the nuances of the policy, but this is getting looked at. Thanks for reporting!
