> The problem is that this biases the statistics due to the 14-day window: everyone who buys a new iPhone goes to the App Store in order to download some "staple apps" How do you know that’s how Apple measures OS version share? Why would Apple limit itself to only measuring when users open the App Store? Any iOS device that ever connects to the Internet checks in with Apple to be activated and registered. After that, iOS regularly checks for OS and app updates. If I own an iOS device that I never update and never visit the App Store on, that device will still check for updates and will transmit version data to Apple. Also, because every iOS device has a unique ID, more active users won‘t be counted double.
