[$] Goodbye FLoC, hello Topics

Back in May, we looked at a Google proposalto replace third-partycookies with something called the"Federated Learning of Cohorts"(FLoC). Third-party cookies were once used to track users all over the webso that advertisers could, supposedly, target their ads better, but, of themajor browsers, only Google's Chrome browser fails to block them today. Googletook a fair amount of flak for FLoC, since it was not perceived to be muchof a win for users' privacy-and was mostly a sop to the (Google-dominated)web-advertising industry. Now the company is back with a differentproposal that could, eventually, replace third-party cookies in Chrome: Topics.
