As much as I hate it in the short term, as long as they keep making decisions like this, they will inevitably push people toward alternative app stores.
Want to link from Google’s app store to your app? That’ll be $2–4 per install
"While it isn’t collecting fees yet, Google says it will charge developers $2.85 for every app and $3.65 for every game a user installs within 24 hours of clicking a link that takes you outside Google’s app store to download them outside the Google ecosystem.
Plus, it’ll take a 20 percent cut of any in-app purchases and 10 percent of any auto-renewing subscriptions. Apps still need to be submitted to Google for review, use a Google API to track them, and developers have to report all transactions (including $0 free trials) if they want to participate."
