Besides all of the issues with decades of peer-reviewed studies claiming little to no connection, there is something very strange that the brand name "Tylenol" is EVER used if the supposed culprit is acetaminophen.

TLDR: anti-vax groups want to mainly blame vaccines for autism, and this Tylenol claim takes some of the spotlight away from vaccines.

* the link between vaccines and autism is ridiculously super debunked.

* there is no evidence linking acetaminophen to autism

* frequency of autism diagnosis is growing at a considerable rate: https://en.m.wikipedia.org/wiki/Epidemiology_of_autism

* males are diagnosed at a rate of 4.3:1 compared to females

The current evidence suggests challenges in the current diagnostic approach because it does not appear that females less inclined to possess autism though they are diagnosed at such a lower rate. That indicates poor and incomplete means of identification. Despite the greatly increased frequency of overall diagnosed individuals the numbers of impacted persons might actually be quite a bit higher.

My wife works special education for a large public school system and the difference in population, both quantity and diversity, is stunning compared to just a prior generation. You can’t help but wonder if it’s something in the food supply or some other widely distributed factor that compounds over time and impacts either early childhood development or environmental/parental conditions.
