Sorry, I wasn't aware you had objections to proprietary products! After all, this was a thread about Tailscale and alternatives. :) Many people find it painful to setup a VPN network and prefer a managed solution (e.g. Tailscale instead of Wireguard.) Likewise, people have different understandings of what exactly FOSS means and I'm not deeply familiar with the BSL, so I'm not sure whether it would meet your needs.
Best of luck in your search! Maybe take a look at Tinc or Yggdrasil.

My one objection to Nebula is that its Android app is proprietary, and your response is to plug the even more proprietary way to run it?

So it's not FOSS.
