So in order to protect my digital privacy, I should register myself at some alliance's website. It just doesn't make sense.
Either this whole internet advertising thing turns out to be a bubble after all — in that case; let it pop, see if we can't figure out something better. If using ad-blockers and tracker-busters helps achieve that goal; good.
Or we end up with an internet where all users settle somewhere on the privacy spectrum in an uneasy equilibrium. On the one extreme of this spectrum we have those who accept ads served them through exclusive IOS or Android apps and unprotected browsers, and on the other extreme those who refuse to play along and use ad-blockers and other privacy tools, and simply shun services that require you to opt-in to data harvesting (e.g., Facebook and websites that refuse to show content when they detect an ad-blocker).
I think we may currently have the latter — I wonder how stable that situation is.
