looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
I didn't say it does. But for the subject websites, which will be almost all of them eventually, all adblocking or code interactive plugins will be useless.
I can easily see news sites, especially those with any video content, will be impossible to use, because if you look at them without Adblock enabled, they're a mess of ads, it's almost doubtful you can find an article in the page.
This is just laying the groundwork for more unblockable ads.
