I can't cancel GitHub Copilot

Back when Copilot first came out, I immediately disliked it. But I decided to give it a fair shake and tried to evaulate it in good faith. I wasn’t interested in paying for it, but they had a form for FOSS community members to apply for a free subscription, so I filled it out and gave it a shot. Once approved I spent 15 minutes (successfully) convincing it to write a Python script that printed out the lyrics to “All Star” verbatim, and haven’t touched it since. Since then, like clockwork I get an email every month informing me that my subscription has been automatically renewed. > Hi there, > > Thank you for renewing your free access to GitHub Copilot. Your access to GitHub Copilot will be reviewed on 2026-05-31. GitHub Copilot checks eligibility monthly per our policy. No steps are needed on your end. > > We hope you enjoy using GitHub Copilot and participating in the developer community. I’m not being charged for it and so it’s a matter of principle more than anything, but I ought to be able to turn this off. But I cannot find anything in the GitHub settings which would allow me to cancel this free “subscription”. GitHub support has been less than helpful: How do I get rid of this thing!
