Before FLoC: My personal blog was not tracking or profiling any visitors; no JS in use, no 3rd party requests, no logging.
After FLoC: My personal blog is now a data point in in-browser profiling mechanism and contributes to my visitor's profiling.
I did not opt-in for that as a site owner, I can only opt-out now by setting some headers? Just having site on the web is now toxic... WTF?
