Most objections of claims about mass sociogenic illnesses that I've seen have to do with people using it to dismiss behaviour they don't like, often without any real evidence that this is "mass sociogenic illness". Even this article doesn't really make any attempt to disprove a null hypothesis and we basically are required to take these people at their word that a) the behaviour expressed is not consistent with Tourette's and the patients don't actually have it, and b) the source of this is due to the YouTuber mentioned. There's no control group or anything to prove these two facts beyond the author's opinion.
