I like how they are shamelessly trying to rebrand Jason Donenfeld's open source work in order to take the credit and the money for features with salesy names like "mobile IP" that were actually built inside WireGuard from day 1. In fact, I tried it a month ago and I had to uninstall it within the first 24 hours after I noticed the excessive logging eating my disk, the inexplicably high CPU usage, and low bandwidth compared to vanilla WireGuard, even pinging was failing randomly for some mysterious reason. WireGuard is a great piece of software, but Tailscale is a very bad, slow and buggy re-implementation of Zerotier over WireGuard.
