The versions that are probably 90+% of their user base are now free instead of a one time payment. That's probably not as big as it sounds because a lot of the people who might purchase the app have already done so. The (less featureful) browser and desktop apps are subscription, but unless people want the new features they probably won't see huge revenue from those for 3 years when the subscriptions for people who already bought start expiring. I'm not sure, but the desktop app is probably a wrapper for the web app - as someone who bought the Windows Phone version, their native app was barely MVP level. Edit: also where is all this about ads coming from?
