Because I have my own custom domain internally and don’t use tailscale while on I’m on my network physically. But I get the best of both worlds, however I do have Tailscale setup with DNsMasq to set to my domain name anyway instead of using the Tailscale domain

Tailscale with reverse proxy, nothing publicly exposed

This! if I see people ask for alternatives I will recommend them, but I’m currently not going out of my way to force it down anyone’s throat.
