no need for a restrictive license! people can just take an apk and slap ads or malware on top. they do it all the time with fake candy crush apks. So I’m pretty sure they won’t care about this license.
I think that in the license is just a excuse so no one is redistributing the app and they can make money from it.
I don’t claim to know what their true intentions are. But if you want your APK with additional malware removed from any appstore, it for sure helps to have terms which don’t allow ppl to do so.
There is nothing wrong about wanting to earn money, but their approach is the weakest. I did not even see a dialogue asking me for money yet.
