What is "Developer Program Member" on Github.com

This is for developers registered to the GitHub Developer Program (like this GitHub profile, for instance)

Membership is open to individual developers and companies who have:

• A paid GitHub.com personal or organization plan
  (since 2019, you don't need a paid membership anymore)
• An integration in production or development using the GitHub API
• An email address where GitHub users can contact you for support

That allows for:

Staying in the know:

Be the first to know about API changes and try out new features before they launch.

Scratching an itch

Build your own tools that seamlessly integrate with the place you push code every day.
