It appears that I may have reached a wall with Samsung. All of their Android development is strictly from Korea and not in English. I am still going to forward a message I received from @Flohack via email and see if it lands in the right spot.
"That's the path to insignificance. You need to be different in order to make a difference."
I still think that a lot of people's expectations will be crushed if certain "obvious" features are missing. These features do not need to be any different than any other platform. As a matter of fact, if they did act differently, people will be more likely to reject them. Generally these features are things that will leave a bad taste in someone's mouth if they are not there and the 'same' as they are used to. Allowing APK and supporting APK will gloss over 99% of missing features or unrealized open source apps.
I love open source. However, a closed source APK store may help the platform see use beyond hobbyists and push the project forward until more open source apps are created for ubports.
