Maybe ask all the people who would refuse to buy this product because is represents more than one type of person
You misunderstand, or maybe deliberately misrepresent, the concern.
There are many types of people who menstruate but all of them are female. The group that used to be called "women" until that name was taken from us and repackaged to mean something different.
When I used to see a company celebrating all the different ways one can be a woman, a huge variety of people linked only, but also fundamentally, by the bodies we have and the shated experience, good and bad, that come from it, that was inspiring and uplifting.
But I don't see that any more.
The word woman has been taken a way, and what is in its place is a celebration only of our differences. The things that make us the same, that allow us to find joy, support and power in our common experience of being female in a male-dominated world are no longer talked about.
You may see that as simply 'representing more than one type of person' but I see it as a act of power and control. To undefine the reality that female people share is to take away our power to act on that reality.
And I think resisting that act of undefinition is a valid and legitimate thing to do, and a very very long way away from "refusing to be a product because it represents more than one type of person".
