I tried searching for answers as to why these machines are reaching out to numerous locations despite not using PrusaConnect. Location lookup returns the expected Czech, as well as location across the US. I recently also set a friend up with with an Elegoo printer and that was expectedly noisy as hell, but I was surprised with Prusa being the 'privacy pick'.

For those curious, here's the logs since about midnight, it seemingly doesn't talk during the day.

Probably some legit uses eg direct from file prints with filename and timestamp, but also there's the yellow tracking dots: https://en.wikipedia.org/wiki/Printer_tracking_dots

Printer isn't responsible for timestamps on your document. If that would be regarding tracking dots, then block it anyway, right? And if it's a 3d printer then it still doesn't need to have correct synchronized time, it only needs to be able to count how the time passes.
