I think there's a lot of room for devs that will stand for their users. My friend is actually releasing a pretty killer, no holds barred blocker (it's in the approval process):

Halcyon Blocker: http://www.halcyonblocker.com

He's the only one I've seen come forward saying he's 100% committed to privacy and his app does not download anything. He curates the lists himself (I've helped profiling some of his block rules).

I have a beta and it's fast, clean, and works. Can't wait for it to come out. He's pretty excited too.
