Polar asks you to grant "act on your behalf" permissions to your Github. As someone who has both professional and open source projects at Github, that's a definite deal breaker
Most of our API integration is purely about synchronising repositories, issues & PRs (read-only). With the exception of 2 things. 1) Inject the Polar badge. We then edit the issue body to append it at the bottom. 2) You can explicitly post a comment as yourself via Polar when you badge an issue, but this is entirely optional and merely a convenience feature would you want to. Requires manual & clear action.
