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 think the point is if website operators start supporting this you might not have a choice but to use Chrome, if you want to browse any reasonably popular web site.
Then I will stop browsing them? I stopped using Facebook, Twitter, and Reddit quite easily. I can do it with others if they're going to go down this route.
Hope you never need to read the news, access your bank account, or buy anything online then.
If my non us bank forces me to use Chrome in order to access my account online, they're gonna get a call from me
