      Let's not hyperbolize; I've been working for years to move everything to HTTPS/TLS. It is the most important thing we can do to protect traffic, and I never claimed that it wasn't. But TLS will never obscure the destination or quantity of your traffic, or its traffic patterns.

      Concur 100%. But an apparent conflict emerges when collection is shifted from one org to another, for money. And like the Firefox DoH move, it centralizes visibility - and exploitability and profit motive - for the data. There's no Let's Encrypt of VPNs (unless you count Tor).

      There is no free-as-in-beer VPN like Let's Encrypt is for certificates, but there are lots of good ways for people to roll their own for free. One great option is Algo VPN, which should work on just about any cloud provider (or home network) in the world. :)

      Agreed, but it's beyond most people's capability. Perhaps close tothe same order of magnitude as the people who can truly judge the threat model.

      There's a difference between those two things, this is just proxying your traffic through a bandwidth reseller. It's dangerous to conflate these, one is just cynically shuffling bits from one untrusted network to another to extract revenue, the other actually has value. 🤷🏻‍♂️

      Do I trust Cloudflare more than coffeeshop wifi? Yes. Do I trust Google not to use my IP to target things at me when I'm otherwise taking measures to limit tracking? No. Do I think a single-hop VPN is going to give me a ton of privacy? No. Do we all want HTTPS everywhere? Yes.

      If you want to direct your passion in a direction which will probably protect more traffic than anything else, could you poke the appropriate people to get Google to preload HSTS?https://twitter.com/ericlaw/status/1201645830173872130 …

      What is the value of HSTS if you're on a trusted network?

          Beyond the fact that we're not always on trusted networks, we could say, performance?

          Sounds like you need to get out your wallet, a trusted network is just $4.99 away. 😂
