t's certainly one of many possible root causes which someone doing an
AAR on an event like this should be thinking about, and looking for in their
evaluation of the data they see.

And I'm sure they are and will.

By the time that post was made, the vendor had shared multiple updates about what the actual cause seemed to be, which were very plausible. An unaffiliated 3rd party stating 'maybe an attack!' when there has been no observation or information shared that even remotely points to that simply spreads FUD for no reason. 

I respectfully disagree.

He didn't *accuse* anyone, which would be out of bounds.
