worse than this is that if you fork a repo that has actions, the actions will run on your account as well - which is completely unnecessary. I have all sorts of stale forks that are just churning away with actions that I dont care about at all because I am not getting charged.

The solution, of course, is not to simply start charging for all actions, because then everyone would wake up to all sorts of mystery charges. They'd need to notify that forked actions would be turned off and then opt-in for paid actions.
