Why is Cloudflare more trustworthy with my browsing habits? I have no contract with them and no agreements on what they may do with my internet activity. I have no contract stating how the data is to be used, how long it is to be kept or whom it may be shared with or sold to. For all I know they could sell that data right back to Comcast. Or worse, they could feed it into a ML training program for a social credit system for future use.
It's not widely rolled out yet, but it exists and it will be in the future.
> Why is Cloudflare more trustworthy with my browsing habits?
Because of a comparison of Cloudflare's and Comcast's past track record of privacy-related matters.
Cloudflare's origins are lesser known, likely even to those currently working for them. That doesn't really matter for this purpose I suppose. Former volunteer for their previous honeypot project
In the end, I have no contracts with anyone stating how my data may be (ab)used or how long it will exist. So instead of one company potentially abusing my data, now it is two. There is really no way around that other than to not participate. My personal preference is to assume the Only Two Rules. [1]
In full disclosure, I use neither of those services for DNS but my I would not expect non-HN people to use my convoluted process combining open source VPN meshes, dozens of unbound caches and dozens on many VPS providers that talk to upstream DoT resolvers with cron jobs that pre-cache thousands of domains in random orders using "shuf" that I do not visit and dozens that I do visit and unbound configured to both override min-ttl and to hold onto 0-ttl records until requested again and running the same cron jobs on my home firewalls that talk to those VPS nodes over DoT and Tinc.

eSNI/ECH is a thing.
> Now instead of Comcast it is Comcast and Cloudflare that can analyze ones behavior.
No, because of the above, it'd be just Cloudflare instead of just Comcast, and there's two reasons to like that better: that Cloudflare is more trustworthy, and that Cloudflare doesn't know the real person behind the IP address like Comcast does.
> One place DoH might make sense is in an organization such as a college campus or company that enable fascist firewall rules but have not yet blocked DoH/DoT. Or maybe non-technical parents using a consumer router to block content.
It definitely does make sense in those places, but they're far from the only ones.
