I don't think people have a problem with they/them I think they had more of a problem with people inventing pronouns like zey/zim etc.

I personally find "it/its" pronouns a bit problematic as well. They were often used to bully kids that were a bit outside gender norms growing up. So to me, these pronouns will always sound a bit derogatory to me
