Someone from GitHub reached out to me because of this comment and said they were fixing it. The problem is that Racket's license file isn't simple enough for their automated tools.
This is curious - I maintain 2 projects with 2k cumulative stars, and I was able to claim the free access. Wonder what the metric is? Maybe creation date has something to do with it?
I get " Congratulations! You are eligible to use GitHub Copilot for free." that was unexpected but in retrospect https://github.com/NixOS/nixpkgs/ is pretty popular. (Currently 9.8k stars)
Yeah that just redirects me to the paid page. I do wish the criteria were a little more transparent.
I have a repository with 625 stars, but it redirects to the subscription page.
Reporting on my own experience, I got access to Copilot a few days after it was announced and am currently not expected to pay for it.
I started a project that currently has 9.4k stars (now mostly maintained by someone else), and still maintain a project that has 2.5k stars.
