"The general scam of unrealistic promises then under-delivering" is how the richest man on the planet amassed his wealth. OP is doing the exact same thing he's accusing other people of doing, focusing too much on identity.

Holmes surely used her gender as a tool the same way all these striving psychopaths will use whatever is at their disposal, but if it wasn't her gender, it just would have been something else. And singling out her gender as uniquely responsible will do more harm than good as it will be used as a cudgel against all future women founders in a way someone like Musk or Sam Bankman-Fried won't for men. Or maybe this early xkcd[1] put it better.
