I don't think that is real. The message that was supposedly posted, has obvious grammar mistakes. Ex. "Google make sense"? Do you know how much he is actually worth. I went to a university where my professor worked formally at Google, and she explained in detail their strict policies that have to deal with intellectual property. They basically own your mind and everything you think of during your employment with Google. Therefore, it's very difficult to work on many projects at once while working at Google. I don't think someone working with so many projects and having already a huge presence would work for Google. It doesn't make any sense.
