if someone publicly violates Halacha, knowingly or unknowingly, shouldn’t there be some public outcry to set things straight so that everyone knows it’s not allowed?
I don’t think anybody here considers Ivanka Trump the arbitrator of what is or is not Halachicly permissible. So even if she did rely on an eyebrow-raising heter, I’m not convinced that it’s necessary to publicly denounce her actions.
