It fails to mention that the CIA had an internal hunt for the contractors which leaked the "Vault7" arsenal - confirming that indeed it was a contractor and indeed that they had mishandled the arsenal by providing global access to the weapon cache.
It also failed to mention the full original story provided by the Shadow Brokers and those that reported on them: that NSA had (similarly) mishandled hacking tools by loading too many of them onto attack staging servers. This story has not changed, nor have the recent publications contradicted it. In fact the Shadow Brokers said exactly what they were going to publish when they first went public and have followed through with what they said they were going to publish exactly.
The author speculates and conspires that both of these must be Russia. Mostly it's the standard fare conspiracy theorist "to whose benefit" but it's clear the author doesn't understand whether and how Russia would benefit from these disclosures.
Finally, after all the public panic induced over "Russian hacking" during the election, there's been no intelligence summary, statement, or even Congressional statement to the affect that either the Shadow Brokers or the Vault7 leaks are in any way attributed to Russia. Wouldn't that have been fuel for that fire?
My guess is that the Shadow Brokers are a criminal organization with informal relationships with state intelligence services. My guess is that Vault7 was a CIA and contractor who shared the massive trove too broadly, where it ended up in the hands of the Wikileaks journalism reporting outlet.
The author appeals to Occam's Razor only by name. The lack of careful analysis in the article insists, unfortunately, in using unfounded speculation in the place of evidence, and horror, to then appeal to Occam's Razor on behalf of assumptions.
