I know it's not exactly what you're asking for (it's non-mobile and it's not exactly an ad blocker), but this seems like a good opportunity to plug the EFF's Privacy Badger.
I do not think that the eff want to help to make the web a playground for big companies only. They do not have anything against small publishers, so why should they develop a adblocker?
Developing an application to block all tracking scripts would technically contain an ad blocker as a subset.
