I am an Application developer who has always had faith in Windows Phone and kept all of my apps exclusive to this platform. I have released apps like Atmosphere, which has been featured here on WPCentral and the Windows Store multiple times and receives over 10,000 downloads every two weeks. In the past, I have released apps that patched holes in WP such as Speech, which was essentially "Cortana before Cortana". The point is, I am extremely loyal to the WP8 platform and have developed for it even during the darkest times when every other developer was porting to android and iOS. The McLaren news, coupled with the latest news about layoffs of software teams, cancellation of feature phones that paved the way for new smartphone users to adopt WP8, among other things, sends one single, chilling message about the future of windows phone - that the future simply does not exist.
Windows Phone is struggling with marketshare now - when people were hyped and excited for features like Cortana, 8.1, and the MCLaren. This is the time when windows phone should be flourishing. But it isn't. Now, following this news, I can't even begin to imagine the fallout. Initial comments are reporting that people are quitting windows phone en masse, people who follow this website, and the ONLY people that follow this website are loyal WP8.1 users.
If people that have been loyal to the platform for years are leaving, imagine regular smartphone users who buy the most heavily advertised item on the market. These WP users will flock to the next generation of phones, such as the iPhone 6 and the next Android phones, not even giving WP a single thought. Why? Because there is nothing competitive on the market for the user to buy. No one wants a one-generation-old "flagship" device. And when the only WP8.1 flagship device is an outdated flagship device, that translates into sales stalling to a halt.
I'm still deciding if I will continue developing for Windows, but I am most certanly not staying with it. Microsoft might as well have comitted suicide with some of these recent news stories, and when MS commits suicide, users and developers leave.
