I trust Cloudflare and Google (the other major DoH proponent) not to sell my data, because they have no need to do so. They are subject to law enforcement inquiries just like everyone else, so this does nothing for privacy in that regard (and actually increases the attack surface). This also does not separate who can see your DNS from who can see your traffic, in fact it consolidates it, and this is why both Google (who controls the browser) and Cloudflare (who serves a large portion of the internet) are proponents of it. It allows them to aggregate DNS information alongside request information in a way they could not previously. I am aware that they both have policies in place which purport to prevent this behavior. It would certainly not be the first time Google violates their stated policies in the mission of serving advertisements, or the first time Cloudflare aggressively consolidates internet infrastructure to the detriment of the open web.
