That might be true... but the "lists" will be third party or user generated, NOT BY MS. A tool is being offered that even MS and us webmasters, too, even the privacy nutz, know the average Joe Clueless User will never bother to train/build/download/attach-to. I think this is a grand idea, and will be out (probably) before the FCC orders browser makers to install such capability. What worries me with the gubermint (sic) will supply the "Don't Ask", er "Don't Track" list which will come complete with their "white list"...

^{Dang, that tin foil hat is getting awful tight!}

While part of above is tongue-in-cheek, part is not: Joe User will have to TURN IT ON and then train it... and how many Joe Users do you know smart enough, or even inspired enough, to do that?
