And if I remember correctly, ZT was initially created to provide something like this "New Internet" concept that Tailscale has apparently recently discovered, except they called it "Earth" and abandoned it in 2023.
(Some things don't change, I guess.)
It's still proprietary if you self-host it, I was thinking in particular that tailscale uses Wireguard and Zerotier uses something custom, i.e. proprietary. Note that the context was:
> The internet succeeded because it was built on standards and was completely free. With Tailscale, I get wireguard is open source and we have things like Headscale. But [...]
to which the commenter I replied to asked of alternatives. So I wasn't saying tailscale great and open and standards compliant, and Zerotier not; I was saying it's the obvious competitor but if that's your problem with tailscale then it's if anything worse in that regard.
I didn't intend to leave to implication the fact that Tailscale is node-to-node, or that it is is not hub-and-spoke.
(I even had this up in a browser tab when I wrote that previous comment: https://tailscale.com/blog/how-tailscale-works)
