Remember Three's plans to offer ad blocking to its customers
[webmasterworld.com]? It seems the E.U. has made it clear that ad blocking would violate net neutrality.
Whilst I support the option of opting out of tracking and advertising, I would still expect to pay for the services in some shape or form, perhaps via subscription. To block ad-supported services entirely is a route to the loss of a service. It's an option most of us don't have right now for the vast majority of services.
