Tough
I am not a proponent of DNS-over-HTTPS, but on the other hand it is just another application that runs using the internet as transport. Users are free to use it if they want to, and it is not for network backbones to pick and choose what to allow. This is sadly why new protocols like SCTP have not been able to gain traction, because a lot of operators just block them. At the end of the day no one person or organization can make the decision for the rest of the internet. Every day I get more and more surprised it still works at all.
Biting the hand that feeds IT
