Have you tried AdBlock+, Ghostery, etc.? Assuming you can even install these kinds of things on the public property... Of course, there are Flash blockers, also. My favorite is Glimmerblocker, a System Pref.
While those and other ads can be very frustrating, I just think "ad-free" is too close to the only barely defeated SOPA and PIPA bills that were defeated last year. It would establish a minimum fee for accessing the web. We may not live in a third-world country, but the web still has the basic idea of it being a "World Wide" asset.
While I would support changing how the Internet is
regulated (from basically none right now!), I don't think setting a fee mainly to block ads is appropriate. With that method, the people/corporations are still being paid but the control is still not in the hands of the users. There is, at least, a 'mute' button on most remotes!
I think the question is becoming; do we want the web to become another commercial "Media" or remain/return to a massively available, 'people-owned' commodity and source of information. I gotta go back into into my "ivory tower"...
You raise an interesting question, of course! Could there be a similar but lower fee covering only animation ads...
