Honestly, at the risk of committing No True Scotsman, I feel like the flow demonstrated in this blog post just.. isn't SSO to begin with, actually. It may be using SSO infrastructure, but if you have to login twice, use 2fa twice, to log in to one thing, then it's Two Sign On or something.

So while I don't think the thrust of the post is wrong in general, it's an odd example.

> GitHub's justification is that contributions on enterprise projects should be visible on personal accounts.

Really the thing that sucks here is something that hasn't really been well solved and is only tangentially related to SSO: Multiple linked identities under one or more logical accounts. No site does this well, and SSO is an insufficient tool to help - the entire mechanism of identity on the web is working against it.
