Conceptually, they are similar, but based on what I understand the implications are very different based on how data is collected and who it is available to. Apple ad targeting: - collected from device info, purchases made from Apple (apps, shows, movies, books, etc.), and app store searches - used to serve ads in Apple apps (App Store, Stocks, News), so while Apple knows what segment you're in, it's hard to see how that's any worse than what they already know about you (assuming you trust Apple with your info, which I assume you mostly do if you use Apple devices) Google Floc: - collected from all of your browsing history in Chrome, not just on Google properties - your Floc ID is available not just to Google, but to every site you visit because Chrome serves it up. This means any site would have immediate access to your interests and demographics. Say you sign up for a site with your name or other identifying information, now they can link your personal information with your interests and browsing habits. So now you don't only have to trust Google, but you have to trust every entity you interact with on Chrome.
