I'd love to have someone else chime in on this because I did some spelunking and am not sure if this comment is true.

I checked my DNS logs and saw zero attempts to resolve `log.tailscale.com` having ran tailscale for many years (I added it to a blocklist anyway). From their admin panel, it appears "networking logging" requires paying for Premium[0], so it's not being used for free users (or Personal Pro).

Also, from looking at some source code (because the docs don't include this), I discovered you can disable logging for the macOS App Store client by doing:

     echo "TS_NO_LOGS_NO_SUPPORT=true" > ~/Library/Containers/io.tailscale.ipn.macos.network-extension/Data/tailscaled-env.txt
