The points might have been valid but the language is not instilling any kind of confidence: "This is an ENTERPRISE MILITARY GRADE Encrypted setup." doesn't exactly make it seem like a security researcher who knows what they're talking about. And add many other words capitalised for maximum shock effect: "imagine you were meeting up with someone like an EX-LOVER your partner may not approve of"
It all sounds very much FUD and biased. If you do a good analysis, this is not how you present it.
The main points he really makes are poor endpoint security (not uncommon in this market, as many such networks have been breached) and noticed some suspicious traffic which is indeed a telltale that something more is going on.
But it sounds way too much like someone with 'skin in the game' was trying to spin it and turned out to be right.
