uBlock Origin does that and way more. That's just wrong lol

Posted this in another comment, but this is why:

Thanks to disclosures from Google Security Team, we are changing the way Privacy Badger works by default in order to protect you better. Privacy Badger used to learn about trackers as you browsed the Web. Now, we are turning “local learning” off by default, as it may make you more identifiable to websites or other actors.

From now on, Privacy Badger will rely solely on its “Badger Sett” pre-trained list of tracking domains to perform blocking by default. Furthermore, Privacy Badger’s tracker database will be refreshed periodically with the latest pre-trained definitions. This means, moving forward, all Privacy Badgers will default to relying on the same learned list of trackers for blocking.

It's just using filters like uBlock Origin since the training was considered a critical security issue that fundamentally broken. The article is the devs talking about it in more indepth.

Privacy Badger also relies on blocklists.
