I don't believe this is fake, as much as I wish it was. They are still updating their Twitter and status blogs and I'd assume if it was fake, they'd see it and at least delete it. I've attempted calling and speaking with them directly through various direct extensions but no one answers.
I personally vouch that this isn't fake. (But anyone familiar with Alan's work could tell that just from reading his comments here—who could possibly fake these?)
Its "Fake" in the context of the original post's claims.
And FYI I did post a comment at-first but hardly anyone noticed it (that includes you too).. probably because the original post already had over a 90 comments and people didn't bother to go through all of them.
And I could already find some online websites and tech news blogs starting to pick this news up from here and spread it on the internet. This kind of news spreads so virally! So I made a post out of it so that people notice it. And they did. Mission accomplished :)
