The stated problem is that there are few providers, as for the offending party - Firefox, it's they've defaulted to a company based in the US or a 14 Eyes member. It doesn't feel right to address the issue by blaming the DoH, or Firefox, as they are not defaulting to the prime evil - Google. I believe the better suggestion here to say is to set up own DoH servers, urge related parties to opensource their own implementation if there's none.
