You get content that costs someone resources to create and give them nothing not even the ad revenue.
I use a click-to-play plug-in, not an ad blocker per se. This is because I'm willing to give them ad revenue, so long as the ads are static (text or PNG/JPEG), as opposed to ads that are animated in a CPU-hogging and data-quota-consuming manner (Flash, video, or Flash video). Yet a lot of sites don't get the hint, and they continue to serve what I see as a white box with a Flash Player logo inside instead of noticing that the Flash ad isn't playing and replacing it with a static ad. Am I still a freeloader?
Increasingly there is only one viable solution. Vote with your wallet. Period. No cable, no movies, no music. Nothing.
I don't see how that can be made to work for most people without something drastic like joining the Amish. For "no cable", how would people living outside the range of fiber or fast DSL get broadband Internet without cable? For "no music", how can you do your shopping if part of what you pay for the products that the store sells goes toward licensing the background music played over the speakers in the store's ceiling? And if even if you choose to write your own music instead, what can you do to make sure that you didn't accidentally copy something created in the past 95 years?
