Service to turn git repository into a lead magnet or subscription benefit.

I've been thinking a lot about software development youtube channels and online courses recently. I thought it might be a cool feature for youtube channels to use their git repository as a lead magnet to build their email list. You put a link in the video description and once the user enters their email address they get access.

You could also do something similar with Patreon and give people access at a certain donation amount.

What do you think?
