I think it’s a very difficult task to try and interpret findings without being influenced by contemporary stereotypes. As you mention, there have been voices in the past decades of archeologists, anthropologists, etc who do a dissent job in trying to just examine the findings.

Others -unfortunately- try to fit the findings into a preconceived narrative. To my understanding “man the hunter hypothesis” is one of those, because as it is mentioned in the article:

the idea that all hunters were male has been bolstered by studies of the few present-day groups of hunter gatherers such as the Hadza of Tanzania and San of southern Africa.

And I would argue that it was a very limited research based on a few (not the few) of those hunter-gatherer groups that are/were considered contemporary.
