It does not allow blocking Google\any tracking and Google ads, essentially, and gives the Ad industry (and malware) a way to circumvent the blocker with modern tech, because it is a non smart ad blocker but a dumb filter list from 2002.
This is fully intended to give Google the ability to use sophisticated scripts to serve ads and track you despite blocking. Everything else Google says about this is bull!
They probably already have the tech set up. And that real blocking still works for Enterprisr customers is the nail in thr coffin.
If you care about a usable Web, STOP USING CHROME.
Google is has become the #1 anti user and anti freedom company. They want to make money from Ads and tracking, so dont think they will allow you to block ads.
