Announcing Privacy Badger for Safari on macOS
I like that Privacy Badger decides on its own. It watches which domains track you across sites and then starts blocking the ones that won't take no for an answer, no blocklist to maintain and no humans to keep up with the arms race. That algorithmic stubbornness is the part that feels like a glimpse of where ad-blocking is headed, software that builds a case against each tracker rather than just reading from a list.
The version requirement is the catch. Safari 26.5 is a moving target, and by the time most people update, Apple will likely have shifted the goalposts again. I'd want to know how long EFF expects to keep pace with Safari's changes, because that has been the graveyard of more than one good extension.
Still, the bigger story is the 4 million people already using it and what they represent. Every install is a small refusal to be treated as a product, and putting that tool in front of Safari's user base changes the math for data brokers. I don't know if it will move the needle on surveillance as a whole, but it makes the refusal a little easier to act on.
