I don’t quite get what changing the name would achieve in this scenario? I might be misunderstanding what you mean though. That being said, this was a suggested change 2 months ago within the community, so very unlikely to be any motivation behind it other than genuine change to clarify the feature. https://bugzilla.mozilla.org/show_bug.cgi?id=1924493
Changes it to a more friendlier term, it saying copy without tracking is acknowledging that the site is using tracking data, where would the new terminology if you don’t know what those parameters are then you just think it’s a shorter link.
Neither changes the fact that it’s happening in the first place, but one is directly addressing the elephant in the room where one is hiding under the rug
That being said reading that link, I do agree with some of the complaints that they have, but I still think it should have remained the same because that’s exactly what the system does. It best attempts to remove tracking information from the URI
