> Fun fact: Tailscale have an almost-assuredly-accurate count of Headscale users due to how few people disable the Tailscale client's telemetry which by default sends them real-time events about everything you do on a Headscale network. See KB1011: https://tailscale.com/kb/1011/log-mesh-traffic

That is not true. We actually instruct all the clients to send no logs - since at least three years:

And also in the config example:

That said, I would have loved to know how many nodes use Headscale... :)
