It seems:
1. Both App Stores grew revenue at essentially the same rate.
2. Customers are basically downloading the same apps, regardless of ecosystem.
3. Both customer bases seem to have a strong affinity for Facebook and their properties
4. Tech nerds may claim aversion, but the public seems addicted to social media
5. China has a huge influence on the App Store.
6. IAP is games.
A fabulous summary.
It also shows that those constantly exclaiming "Privacy!" on public forums are in the absolute minority.
Interesting also to see Telegram above Snapchat.
