If you don't use a very sophisticated blocking system (for example uBlock Origin in medium mode + pihole) the data is being collected independently of serving ads. While it will be used for Realtime Bidding and ad-retargeting, the data itself is very valuable in lots of other ways, and even though I am not an expert I fear that in many ways personalized profiles attached to your real world self can already be created and sold to those who want to know more about you. Even with such a blocking system as described above there will be some data send. So the stricter the User agent, the better for the user. Making fingerprinting more difficult, which is what Safari will do with ITP 2.0, is something that is very important regardless of blocking ads, as first parties want to track you too independent of ads. - https://github.com/gorhill/uBlock/wiki/Blocking-mode:-medium-mode https://github.com/gorhill/uBlock/wiki/Blocking-mode:-medium... - pi-hole.net
