Hobby developers (which were the vast majority of apps int the first days of the ios app store) were most definitely deterred. That was Windows 8, not even 8.1, which was a complete joke of an operating system. The first wave of ios apps came from Mac developers; then people started buying macs to build ios apps. The first wave of WP apps didn't come .... because there were very few people who could build an app on their existing dev environment (win8 uptake among developers was abysmal). Furthermore, the first ios wave actually came from the homebrew scene, which organically grew and produced ios apps even before Apple provided an SDK; There was never such enthusiasm for MS to build on. The WP8 requirement was just adding insult to injury.
