If you use Github, you should have an email from ~2 days ago with the subject "Important Update to GitHub Copilot Interaction Data Usage Policy". Easy to skip over assuming it's just one of a million private policy update emails.
If you don't use Github Copilot, this shouldn't effect you, and may be why you got no email. The current headline is fairly misleading--it's about Copilot usage, not private repos per se.
