what? github enterprise is 1/5 that cost. and what about github actions? they provide 50k minutes/month for enterprise https://github.com/features/actions
To be fair, GitHub Actions is a relatively new thing and I'm not even sure it was already opened to the general public (that is, to anyone who didn't signed up for the beta). It's understandable if GitHub Actions isn't yet a part of the general public's mental landscape.
