If they want to actually improve user experience they can always include uBlock Origin by default - its permissive license should allow this just fine.
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?
