For example, it points out that DoH doesn't really protect privacy from ISPs because ISPs can still see what the users are doing because the ISPs route the traffic. Then, it claims that DoH weakens security because it would let users get around malware blacklists. However, this is mostly nonsense for the same reason. Malware (and other legitimate blacklisting) can and should be blocked even when hard-coded IP addresses are used.

The point about the logistics is very true, though. I won't use DoH at home because I operate my own DNS that contains intranet addresses not accessible from the outside Internet. DoH in Firefox would break those services.
