As an Android game dev, I'm not sure I like it. How is this not distributing my copyrighted material without permission? Just because my app is available free of charge, doesn't mean it can be freely distributed by the website owner. And it's not just a control issue, it creates actual problems for me as a developer. It makes it easier to create rip-off's of my APK or adding malware and rehosting the package, or extracting my sound and art assets. And you know some of these users will be contacting me for support when something breaks because they are sideloading the app. I also can't automatically roll out new versions of the app to these users, causing fragmentation of the user base or bad reviews and ill will if I have to ban their old app version from my online backend. While all of the above already happens to some degree today, I don't look forward to it becoming common practice. I'd actually prefer you not download my completely free (with no ads or IAPs) game at all if you won't do it through a channel I've setup.
