to me adblock does all this.
1. content neutrality - it my have started as an "ad blocker" but now blocks so much unneeded web elements that it truely enhances performance. those things it is blocking are more then advertising, and also includes tracking information
2. transparency and control - user is able to blacklist/whitelist any site at any time
3. openness - user is able to view complete list of blocked elements at anytime.
so mozilla is ok with adblock/ghostery etc. IMHO anyway
