I notice that the Haredi rabbis listed in the ad are not actually part of the event. They were just asked to attend. Which means that they have either said no or they have not gotten back to the fine people at Ateret Shlomo (which is another way of saying no).
I should send out spam emails:
Read Izgad! The blog of Rabbi Dovid Landesman, Rabbi Shalom Carmy and Malcolm Gladwell.
(At least one of them actually reads this blog and every one of them would be welcome to offer a guest post if they so wished.)
You have to give Kupat Ha'ir credit. They at least go through the trouble to get Haredi rabbis to offer blurbs in favor of their idolatry.
