It’s not like I’d be running everything over Tor. DNS requests for newly‐visited domains would slow down, but unbound’s prefetch feature would keep popular frequently‐used domains cached. Adding one of those advertising domain blacklists might help performance too.
The point would be to keep Cloudflare from being able to track my DNS requests.
A VPN gives you little protection against browser fingerprinting, which may alone leak enough information about you to identify you. Also privacy-by-policy is in no way near privacy-by-design. If you want privacy, use the Tor Browser.
