regarding Privacy:
Yes, Linux definitely has a lot less Telemetry. But: I would argue that without Security you can’t have Privacy.
I would rather give MS their Telemetry than risk a random Attacker getting Access to my entire Computer and all the Data on it.
But “can you have Privacy without Security?” is kind of a Philosophical Question and heavily depends on subjective Definitions of what Privacy is to you, so I don’t think we’ll reach an Agreement there.
