I think it’s offensive to women that they apologized. The problem is that (like most people in the world who aren’t Frum Jews, and even some Frum Jews), they have no understanding of what tznius is about. Therefore, they probably thought it was demeaning to women that there were no pictures of women, and that is probably why they felt a need to apologize.
The problem is that they are wrong -tznius is not demeaning to women. It’s a lack of tznius that is demeaning to women.
I can see why someone who did not have a Torah chinuch might not understand that when it comes to certain tznius issues, but when it comes to advertising, it should be very obvious to anyone.
As you pointed out,LB, the feminists should be up in arms over this.
