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 )

and also some github docs
I quit the internet before I quit Firefox.
Same. I feel like this will just push me offline. I refuse to relinquish control over my system.
