I think Tailscale have the right approach by knowing their customer — someone who is happy to have a trusted 3rd party administer parts of their VPN in return for time and cost saving. There are a few here who can't have that, so they instead invest their time into a custom setup with WireGuard which is fine, but for those of us who don't require that level of assurance (there are bigger attack vectors to worry about), Tailscale is fantastic. Quick, easy, and mostly works out of the box.
