Not to defend this behaviour, but a lot of clouds SaaS do require you to pay for both ”management” and for the actual resources. And if you’re using vms in their cloud, you pay twice.

For example, Azure has had a script runner service for ages that you can hook up to your ”own” vm, by installing an agent. But then you pay double, the fee (per second) for the service as long as the script is running, and the fee (per second) for the vm in azure as long as it exists. So, as with GitHub actions, it’s cheaper to run it on their provided crap instances.

To get rid of the double costs I guess you could install your own CI server and agents, that polls the GitHub repo, but then you don’t get the integration in their web gui. That was what you did before gh actions came around, a local Jenkins for example.
