In the context of switching from Chrome? No, I very much did not. On the privacy front, I'm absolutely convinced that switching from Chrome to Firefox is an upgrade even if you don't do stuff like this.

This is my entire point. Yes, you can tweak Firefox to the max and yes you can complain about the more questionable stuff Mozilla has done, but compared to the privacy/goodness you get just from ditching Chrome (or Edge for that matter), all that is pretty marginal.

Disabling anonymous telemetry just harms the project. It doesn't give you any "privacy" benefit.
