Cloudflare has a better track record than most ISPs and governments.
Aren't there a bunch of European ISPs applying government enforced DNS blocking?
Seems like this is a very good move for them.
The ISP I run is applying [1] such blocks on our DNS recursors (blocking illegal online gambling domains, as per legal requirements [2]).
I still trust my DNS servers (or those of most ISPs, for that matter) more than I trust Cloudflare. I'd rather have intelligence services go through the effort of infiltrating every single ISP separately to get any useful dragnet intelligence, instead of just one large entity that can illegally collect all traffic from all users of a web browser.
I feel like at least in Europe, a large majority of people would trust their government and local ISP much more than some company halfway over the world with basically no accountancy in your own country, especially an American one since it means your data is basically at the mercy of the US government.
