Okay sorry perhaps I should put it differently...

Don't overplay the privacy provided by DoH it has no effect on the DNS provider so any hint of 'privacy' should be caveated by stating its only as private as the company and country in which that company is founded, and where it operates servers. This is where the clients behaviour is of interest. If it chooses a company's service without giving the user an explicit choice its potentially setting it to be less 'private' than the local providers DNS.  This is particularly true in the EU and countries that have strong data protection laws.

Note, I'm not actually anti-DoH. I, however,  don't want it oversold, nor do I want the implementation to ignore real impacts and risks. I include here the risk of unintended consequences many of which will end up making the 'bad' you are trying to fix worse than it is now.

PS: I know that people use google et al already for DNS. This, however, is a protocol that places privacy front and centre, so it's much more important that clients are clear about what privacy its providing and what privacy it can't provide.
