If they want to actually improve user experience they can always include uBlock Origin by default - its permissive license should allow this just fine.
Despite it being an absolute dumpster fire in other ways, the new firefox android almost has that. It's nice for telling my friends who I've gotten to switch over to just open firefox, open the hamburger and tap addons then addons manager, then tap ublock origin at the top of the list and that's all it takes to get my friends rolling with it. They're all extremely happy with the new firefox and don't notice how webpages are pretty broken in it now.
They could just show users the recommended plugins to install as part of user onboarding .
It is not just about privacy or blocking ads. It is matter of security . I am trust nytimes , I cannot trust every third party whose code nytimes decided to include. Who in turn has included a bunch that nytimes doesn't even know about. How can I trust a website when they themselves do not know what crapware runs?
There is a move toward 1st party proxys as a result of GDPR and similar ruling. Google has already published a framwork or something in that direction. It is not mandatory yet, but when the web moves in that direction there will be no blocking of domains any more. (Technical) Users won't even know that Analytics tracks them.
