Your ask about Moz/Safari I've said quite a few words on elsewhere in this post & on others. I think the far more interesting topic is what a bunch of jackal villains the IAB is. I cannot stress enough how hard a time Google has had trying to preserve any privacy on the net when there is a huge lobbyist group close to regulators pushing so hard to end user privacy. These people have the worst most anti-user outlook imaginable, are up to absolutely no good. My strong language is a just a start on describing how awful the IAB is & what sinister monsters Google has to go to the mat & wrestle to try to preserve user privacy in a post 3rd party cookie world.
Personally I don't think it's right that I get flagged for my previous reply, but I'm glad to have made a better go at my reply this time. https://news.ycombinator.com/item?id=35565707
