The story was discussed heavily few days back and arguably has been one of the biggest news that broke in the tech industry in a while. That's the reason why the article seems to have assumed a whole bunch of stuff.
I suppose the insider-baseball nature of how the story is presented is what makes it hard to follow. These type of articles are often a mishmash of namedropping and assumptions, which ends up distracting from the actual story or the topic itself.
