And yet this privacy invasion wasn't announced or discussed ahead of time, wasn't explicitly presented to the user, and was opt-in by default. These are classic signs of a company who knows what they're doing is wrong, and want to see if maybe they can get away with it.
There is no such thing as "privacy-preserving" ad tech. This is a betrayal of the Firefox userbase, and pretending otherwise is disingenuous at best.
@narinarinari Except it was announced - two years ago, even on the mainline Mozilla blog (you just didn't care enough to interact with it). And except it is privacy-preserving (if you disagree, then please, publish an article showing how DAP can be reversed or somehow de-anonymized!)
If we wanted to hide it, we'd have hundreds of different ways to do that. None of which would include "adding a visible toggle to the settings", and "add it to the release notes".
