What Tailscale isn't: an anonymity service

Speaking of not being an anonymity service, I stumbled across this ticket on Tailscale’s GitHub. It’s been open for 3 months with no response:

When “Use Tailscale DNS settings” is checked in macOS, Tailscale additionally records all your system’s DNS queries. This means that when this box is checked, on machines where it is installed, Tailscale will collect metadata about your laptop’s routine web browsing, such as when you visit Google.com, and when your server retrieves updates from Ubuntu, your AWS account ID, your EKS endpoints, and other private hash information that appears in domain names. This is your “Internet browsing metadata”.
