It may do so in the big picture, but number of reviews != number of quality reviews. I'd much rather read reviews from people not incentivized to write them, and I'd rather not have to wade through all of the organic results from those that are affiliates to find the ones that are not. Spammy review sites are also Google's problem, and they do a lot to keep them out of rankings. This won't hurt forums though where people candidly share their feedback on apps. I'm not clear how people using CPI installs through shady tactics like malware will suddenly rise to prominence. I can't see an honest reviewer who is reviewing for the sake of it (vs. the paltry affiliate commission) saying "yes, I should review this scummy app that forced its way onto my device." Instead, I think we'll see the rise of reviews from sites that monetize in other ways such as traditional display advertising, email sponsorships, other products, subscriptions, etc. Forums and social will also hopefully have less spam as it becomes less financially viable for the spammers in question.
