“It’s not true anonymity, because that’s a problem Tailscale is not trying to solve.”
Tailscale now resells Mullvad exit nodes at $5 a month for every 5 devices. Tailscale knows who you are through your identity provider, and it runs the control layer that tells your devices which Mullvad server to use. Mullvad on its own ties your account to a number, not a person. Through Tailscale, your privacy VPN sits behind a company that knows exactly who you are.
