Target the platform the paying users are on
That's why Photoshop et al were provided for OS X/MacOS for so long and not just Windows. There were lots of Mac users who were prepared to pay Adobe money for the product.
Winging about Android outnumbering iOS devices ignores the absolute number of users on each platform who may be prepared to spend money on Adobe products. There are demonstrably more PAYING users on the iOS platform (many of the Android devices are cheap throwaway things that either won't run their software or the owners wouldn't consider using it), and it takes less work to develop for so it gets preferential treatment.
