I was commenting on the “as ISPs are not to be trusted” part.  My point was that _some_ ISPs are known to have mucked with responses (by default, without informing users, etc).  Your ISP may not have done this, but others have and that has resulted in a desire to block that sort of behavior. Unfair, perhaps, as it paints all ISPs as equally guilty, but life isn’t fair.

I’d be surprised, given Mozilla’s user base, whether “informing every user” is a viable option — I suspect too many Firefox users wouldn’t even understand what they were being told, much less what to do about it. So they can do nothing and continue to rely on the local infrastructure which has, in some cases (although I gather not your case), been bad or they can take steps to protect their users that technical users may take issue with.  I might agree that Mozilla is making unwarranted decisions for their users, but I can understand the rationale.

AFAIK, Cloudflare’s interest in root servers (the subject of this thread) is (was?) related to the increased attractiveness for peering announcing root server addresses gets them.  I don’t know what value they derive from either their 1.1.1.1 service or the DoH service.
