I suppose You could copy paste the ABP whitelist into ublock origins so you do not forfeit ublock performance advantage.

IMHO you choose yourself the websites you want to whitelist, this way you can give away your privacy for fraction of pennies to the websites you choose to support. What if you want to support a controversial website that has been banned from most conventional advertising networks (for example the piratebay) ?

Then again the trade off between permanent own privacy loss for fraction of pennies make no sense to me.
