It is poorly formatted to be sure, but it also relies strongly on speculation, anonymous sources, and innuendo. I do not put much stock in it. Not just because I don't have a problem with Disney's handling of Star Wars at this point, but more because it is highly repetitive in the same old talking points about how Johnson "jettisoned" Abrams' original plan, or how the Story Group is a cabal running the whole thing.
It smacks of conspiracy level writing, and doesn't even do the solid of providing any proof beyond "anonymous sources." At least most conspiracy theory sites I enjoy cite their sources and information.
