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
Guess why I don’t use the Chrome ecosystem and don’t depend on Google.
This would include YouTube, mail, drive, maps, search which I use daily. And it will be baked into android, and possibly Mac os so it supports the latest standard.
My guess is that sooner or later google chrome will show scary warnings “this site does not support dem, here is a link why this is bad!!!” In the browsers address bar to get users and webmaster to adopt the DRM.
