PPA does not involve sending information about your browsing activities to anyone. This includes Mozilla and our DAP partner (ISRG). Advertisers only receive aggregate information that answers basic questions about the effectiveness of their advertising.
So, let’s say I trust in everything they are saying, which is the absolute best case scenario, then they have done nothing for privacy, because the whole premise that ad networks only care about ex-post measuring the effectiveness of their ads is false. They could have done that long before.
They want to know who you are and what you do so they can sort you in categories and show you specific ads based on those. That’s the service ad networks sell to advertisers. So, tracking as usual will continue.
