Re: Who do you trust?
Creates a part-and-parcel problem, though. If DoH and HTTPS both use the same port, suppose say Cloudflare simply piggybacks DoH on ALL its HTTPS addresses (which includes IPv6 ranges, meaning you can be talking quite a bit of Internet real estate). Then the only practical solution to blocking Cloudflare's DoH is to block Cloudflare, full stop. Only an inward-looking oppressive power (who would be against the likes of Cloudfare in any event) would dare to do that because anyone else risks collateral damage from blocking a provider as big as Cloudflare.
