Sure, but only if you opt-into it. If a browser sends your private information like IP address to a third party, without your consent, that is by default opposite of privacy-respecting. (there is no privacy being respected there).
1. I don't think an IP is particularly identifiable information for a browser vendor - the information they have is "this device currently associated with this IP uses our browser", which is not significant.
2. Just because the IP is sent doesn't mean it's collected and stored. They may drop it as soon as the data gets to the server - meaning that the IP may have been transferred but it in no way is analyzed to attribute any information to you.
User privacy is no longer something you can tiptoe around - it *has* to be informed and opt-in; i.e. if you slipped into someone's bed at night and had sex with them without consent, was it okay?
The point is that we disagree, not that one of us is right. Mozilla isn't using some objective term, they're using one that's highly subjective.
You didn't address the major point I had, which is that they can just drop your IP and not store it. Soooooo, anyway, I'm ignoring the rest of your post because I don't care about the debate, I was just trying to explain that telemetry is privacy respecting.

The point is that you don’t know that and you cannot guarantee it. You just assume the best case.
As analogy: is sending your bank password a privacy problem? You argue no, because they could just throw it away immediately, instead of going on a Christmas shopping spree. That's an insane argument to make.
