Except the article clearly states:
> Amazon wraps your app with code that enables the app to communicate with the Amazon Appstore client to collect analytics, evaluate and enforce program policies, and share aggregated information with you. Your app will always communicate with the Amazon Appstore client when it starts
Now, the original reason to do this might have been benign and well-intentioned, but the result is bad already. This is for now, who says they don't simply add ads like Google [0], or even without the developers knowledge like SF [1] once did? Ubuntu tried to only implement a search and it backfired badly [2], I hope this goes down a similar path.
As a side-note: Of course I'm very happy that competition to the PlayStore is getting some love. This is direly needed. But Microsoft could have gone with F-Droid easily. Trading a bad thing for something worse does not fill me with joy.
