If you’re at that point of not trusting a company, the best practice would be to avoid using their devices or connecting them to your network.

There are plenty of other ways to track and identify users, a company could conceivably bake whatever the hell they want into the operating system and doesn’t need to rely on you creating an account with them to achieve that objective.

I used the term “unhealthy paranoia” due to the logical fallacy that is at play.
