While I agree in spirit, I find this logic around for profit FOSS projects a little backwards sometimes, because it implies forking Tailscale wouldn't save much time.

What makes you think we'd be better off building a competitor to something open source if it has all the features we want now? The reason we don't see open source competitors to big products is not because people are too dumb to try it. It's because it's way, way harder. It makes way more sense to Fork and work from there while we're still getting this momentum from Tailscale.

If you think Headscale is going to have problems keeping up with a private Tailscale, good luck rebuilding Tailscale.
