Yes it does. Basically it says that opera intends to strip out ads from the pages it serves and replace them with new ads. Which new ads? Opera will simply auction the space to the highest bidder. Obviously this will only work for ads that go through its servers, but apparently it controls a large proportion of the mobile proxying/caching market. Sounds nice in theory, not sure whether it will hold up in practice. Note they state explicitly they will NOT perform behavioural advertising.
