How to contact GitHub product managers?

After what happened to Faker.js, I've been trying to find ways to help open source maintainers. As you aware, there was a project on adding terminal ads, but this was not accepted well by the community.

My idea is to make a change to GitHub repo page and show a list sponsors. With their logo, clickable url, some text (if they want). I believe this will be a good advertisement channel for sponsors, it will, for sure, increase their visibility.

I'd push further, GitHub should allow more customizations to repo pages.
