According to the docs[0], you need to log in to Github in order to share a port. Can anyone explain why this would be necessary? I understand it if the port is set up as private (as explained in the doc), but not if it's set up as public. Is the traffic being routed through h Github? 0: https://code.visualstudio.com/docs/editor/port-forwarding

The answer is almost certainly "abuse". Traffic is routed through a "service hosted in Azure" (probably not GitHub specifically). They're just using GitHub sign-in to apply per-user limits etc.
