I find tracking abhorrent. However, the more I read about FLoC, the more I want to also read a blog post that shows just how finely I have been identified. The practice of the theory. Like the browser fingerprinting sites we all know and love. Is there a site out there that shows how poorly this new tech protects my privacy? It would be great to show to people.

The EFF has https://amifloced.org/ https://amifloced.org/ if that helps any.

  This seems to just tell you if the feature is enabled, not what information or interests your FLoC provides? Or does it provide more information on your cohort if it's enabled in your browser? (It wasn't in mine.) There are a lot of scary words and graphics and implications, but I'm not sure this does a good job explaining what the issue with the proposal is or why it's bad for privacy.

    The TLDR seems to boil down to that the EFF will not be able to tell you what information or interests your FLoC provides, but large advertisers and ad companies will be able to - because they run the same code and can read FLoC identifiers off a ton of people. To EFF your floc code is just noise. To large ad networks, they see that people with floc code xxx typically show up on sites a,b,c,d,e,f,g because they have the ability to read floc identifiers originating from those sites.

it will identify you in a group of a few thousands other people.. google said the cohorts should not be too big. the main problem with floc in my opnion is that it extend tracking to sites where no tracking happened before. today to track they need you to go to a site that has an ad or a "social media" button. basically something that make you access their server while telling the site you came from, maybe set some cookie while there so they will know you are you when you access some other site.. if a site does not have any ads or does not have social media buttons they cannot track you there.. the same if you enable adblocking.. now with floc it will use every site you accessed in the last week to calculate your floc.. so they will know what sites you are visiting even if those sites does not have anything that would allow you to be tracked today or if you use adblocker and stop them from tracking by other means..
