While I understand that the OAuth page is meant for all uses of the Github SSO, and the text is likely boilerplate, it's slightly inaccurate (and a potential security scare for eagle-eyed users) to suggest that the Github app isn't from Github.
GitHub Desktop version: 1.0.6

Hi @sbonami, thanks for opening this.
While unfortunate and confusing this is currently expected behavior as the logic which determines what is classified as an app owned or operated by GitHub is based on the organization which published the application. In GitHub Desktop's case, being an open-source application, that organization is 'desktop'. The same goes for applications such as Atom.
Thanks for responding so quickly @niik. I figured as much!
Ran into the same and thought it's some kind of compromised build trying to get access to my repos. Spent some time doube-triple-quadruple-checking what's going on.
While I understand the canonical rationale, I thing from experience point of view you might be able to make some kind of internal alias for that, since, the desktop org is truly "owned or operated by GitHub", because… well… it is:)
