> What if Wikipedia started charging or restricting API access? Wikipedia has a downloadable data dump that would cost almost nothing to serve to Google, and it has an organisational mandate to make that data available. If they decide to charge for access to that I'm sure Google can afford it. Let's not throw around completely unrealistic hypotheticals.
Then my Puzzle Game Redactle (https://redactle.net) would be threatened much like what happened to GeoGusser being charged for Google Maps.
Related to the article: I've also had trouble ranking Redactle on Google because there are a few poorly implemented ad-ridden versions which are part of link farming groups. Many of them pretending to be my 'Redactle Unlimited' brand. Google loves a bunch of spam sites linking to each other more than thousands of links from authenticated users on Reddit, Facebook etc apparently.
