I think it's important to realize that this is basically shifting the whole discussion. What DoH is supposed to provide is privacy from your ISP. It's not claiming to provide privacy from the government, and most people don't expect to have DNS privacy from the government (that's not to say it's not desirable). So this point is basically just misdirection. If your adversary is the United States government, then no, DoH isn't great for you if you're not in the United States and if the US can't get to your ISP / DNS provider anyway, and if your only DoH endpoints are owned by US companies. You also have much bigger problems than DoH is attempting to solve.
