If you click the Raycast link in one of these PRs it links to: https://gh.io/cca-raycast-docs

So I think they’re injecting this as a tip on using Copilot, that just happens to be their integration with Raycast.

I have no idea what their actual partnership with Raycast looks like, maybe this is part of what they offered them? But it’s not a traditional link to another product ad like it appears to be from Raycast being a link.

It's time to make some money with Copilot and one way to do that is with partnerships.

GitHub's docs and blog make use of and feature Raycast, and I'm willing to bet that's the result of a partnership, and not because someone writing docs and blog posts happens to think Raycast is great and keeps bringing it up.

The same way Google advertisers other organisations products.
