The utter rent-seeking audacity of charging by the minute for action runners you run on your own server...

Charge a flat fee per Action, sure. There is a tiny cost on GitHub's part associated with the API calls for starting and stopping, but if my build takes 8 hours on a self-hosted runner there is no more cost to GitHub than it taking 10 seconds.

That's the whole point of self-hosted runners.

Maybe there was more outrage elsewhere, but I was frankly confused at the seeming lack thereof here on Hacker News.
