Exactly. Huge.
To prevent your ISP from monitoring you, give your $$$ to the largest VPN provider in the universe, and have them monitor you instead.
Tailscale partners with Mullvad!
This partnership allows customers of Tailscale to make use of the Mullvad VPN servers as “exit nodes”. This means that while connected to Tailscale, you can access your devices across Tailscale’s mesh network and still route outbound traffic through Mullvad VPN servers.
HUGE.
