I think its more about trust and trust of products, historically we've believed women and children to be weaker and more vulnerable as people which is in turn why we depict them as so in sexist attacks: "Women are not good enough" and men are depicted traditionally as "strong, tough and burly" which I would say is also a wrong and stereotyped point making it harder for many men who are not like that or might need a break but can't because they have to maintain their "tough" image.

Thus Johnson & Johnson breaking that delicate trust over the issue of vulnerable women and children shows them as profiting from the "weak" and "precious" using products they knew were wrong. Society does not look well upon harmful exploitation at the profit of a few but expense of many, especially when you buy talc powder to use for children trusting that it won't harm you.
