I don't know this website but to me there is great chance that it is (Russian?) propaganda spreader.
Opinion is presented as fact that there is nothing to see...
At the opposite, recently there was reports of a strong suspicion of a Russian black ops related to that with a specific set of spies located at a right time in each location where it happened. Around 1000 observation of the Havana syndrome have been reported in different place and time. Even if we can easily assume that a part of the reports are not real Havana syndrome cases.
Real clear science is an American media outfit. It's part of the same media group as Real Clear Politics and was founded in Chicago. There's nothing fringe about skepticism of the Havana syndrome story. Despite Congress dumping loads of money to support agents' health issues claimed to have been due to mysterious and unverified sonic weapons, every medical investigation of these reports has failed to offer any support for it. We lack physical evidence, we lack any sensical motive; all we have is foreign paranoia and hearsay.
I have something like Betteridge's law about anything implying "fact checking" in its title.
What about The Insider's "investigative report" (https://archive.is/KbT6t) or stuff like project PANDORA? I mean, it's not like the other side of the question is massively more trustworthy, but it's not just tabloid conjectures either...
In the end, like for 99% of all past and present events, the only sensible position is "I don't know".
