Isn't this, in some ways, good for the consumer? While some legitimate review sites may be impacted, this would imaginably help cut down on the number of illegitimate spammy review sites that are pushing ad-ridden and malware-ish apps.
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.
Not really, one thing is revenue, another thing is profit.
Those spammy sites pay a lot of money to appear on those clickbait tables that appear at the end of articles. And without guarantee that the user (victim) buys anything.
