> Even more ironic is that NAT got normalized as a security feature — “your devices are hidden!” — which is one of the things that made people resist the thing that would fix it.

That tracks. I briefly looked into the Tailscale website and I thought maybe I was wrong, maybe it's not a NAT/ddns toolchain, maybe it's something more complex that I'm too dumb to understand. But if my thesis that it's NATware is right, it makes sense to market it as a security product, it fooled me for one, but it also passes as a quality product for an organization, and they feel they are getting a security product when they are actually signing the purchase request of a developer that is applying networking techniques they learned from managing a videogame server.
