While this doesn't solve the problem completely, it's interesting that they started. Apple can go all the way down to the system level to anonymize iOS and at make you look like everyone else, much more so than Firefox for instance.<p>Also some shade thrown at Facebook in the screen time demo, they called out Instagram and Facebook as great things to block. Not a full war declaration, just "how about less Facebook".<p>Some examples of why this doesn't completely block everything... All the cell phone companies have unique ids on each device which they seem quite happy to sell. [1] There are many ways to fingerprint people on the web (how fast code is running, gpu speed, touch and scrolling style) that will be wack-a-mole for awhile. Each website that is tracking you now could use it's own cookie to record user behavior and then send it to FB/Google on the backend to link them later. For your phone on wifi, your isp or cable company is selling data based on your mac address and ip address. [2]<p>Great that unlike GDPR, this isn't an enormous pain for every little website in the world. It just makes big company Facebook/Google tracking harder.<p>[1] <a href="https://www.igeeksblog.com/how-to-disable-data-tracking-on-att-verizon-sprint-t-mobile/" rel="nofollow">https://www.igeeksblog.com/how-to-disable-data-tracking-on-a...</a><p>[2] <a href="https://hackernoon.com/what-youre-revealing-to-your-isp-why-a-vpn-isn-t-enough-and-ways-to-avoid-leaking-it-503816542951" rel="nofollow">https://hackernoon.com/what-youre-revealing-to-your-isp-why-...</a>
