My objection is simple: I have to protect my CI queue simply because GitHub chose to count PRs from third party against my project's queue. If they simply counted them against the PR author's quota, this abuse wouldn't be happening in the first place. People would run them in discreet repos as they would gain nothing from forking or opening PRs.

Now instead of counting this CI usage in a way more favorable to project maintainers, they give us a way to manually approve runs before they use our CI. That's good, but still a solution to an artificial problem. I think I would have welcomed more openness about why this way of accounting is necessary, instead of this extra work put on me and labeled as a "help" that I never thought I needed.
