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 am pirating stuffs. They can’t stop me. No other websites can stop me. Piracy sites are not going to use DRM. Firefox + ublock is heaven. Using it even for browsing lemmy as I like the mobile interface better than apps available right now.
Most probably firefox will also bring this or they will lose market share further which is already pretty low.
