> You are costing the service provider valuable resources without giving back anything in return.
No, the service provider is dumping a mass of content at you without asking for payment, and you are selecting which of that content you wish to view (and using an automated tool to implement that decision.)
Now, the service provider may be anticipating that some percentage of users will view the ads, but that's not an bargained-for-exchange, and its generally not a legally binding obligation of any users. It may be a moral gray area, but that's a different issue.
Not under any legal system I am familiar with.
