Because it's not selling well possibly?
The things that you guys love, varies wildly from what the general smartphone buying public is used to. Microsoft has the option of keeping you guys happy and staying at ultra low market share, or making WP friendly and familiar to the world, and increasing their numbers. You guys will get over it, you always do.
Oh.. Come on! You really think, why WP is not doing well is because of UI? Then you would be surprised to know, that it is not beause of UI, but the lack of apps and features. I'll show you a general conversation between me and my friends. I'm a college student and so they are. This will give you a basic acknowledgement of what young people think of WP and why don't they buy it.
My friend - Hi dude. I'm thinking of buying a phone.
Me - Wow. Great. Which phone did you decide on then?
He - Apple is out of my budget, guess it will be any Galaxy or Xperia or even HTC. Not decided yet.
Me - Well, you could try Windows Phone, a great OS!!
He - Ohh.. Let me see your phone.
Me - (show him my 920), I show him the cool Live Tiles, smoothness, soothing animations.
He - That's really great. But, Android is also smooth, my brother has a XYZ phone. It's very good. And Lollipop animations are also very good.
Me - Yeah, but Windows is also good. We have the best cameras.
He - Yeah, but, I've heard there are not much apps for Windows Phone. And Instagram and Twitter are plain bad compared to Android.
Me - (As, I don't lie and don't want my friends to be disappointed after getting the phone.) Well, yeah. You can't upload videos to Instagram yet. You can't edit your past posts on Instagram. You can't change your profile pic and cover photo on Facebook app. Twitter app doesn't show inline images and notifications are broken.
He - And what about Bluetooth?? I heard you can't send files over Bluetooth.
Me - Yes, we can now. Those were WP7 days.
He - And WiFi direct? And USB OTG?
Me - No, WiFi direct is not built into the OS, but there are apps, third party. And no USB OTG either yet, but things can change in future.
He - Dude, why do you think I will get this phone? Agree, it looks good, but no good apps. By the way, I heard there are no official Google apps.
Me - Yeah, no gmail, no Google Plus, no Hangouts, but we have Skype. No YouTube, but we have great third party apps.
He - I don't trust third party apps. And, I heard Skype is much better on Android than Windows Phone, as is Office and Outlook which is recently launched.
Me - (sadly) Meh.. Yeah.
He - Well, Android has more games too, and have variety of options. 930 doesn't have a microSD card and 1520 is very big. You can live with these much limitations, I can't. Sorry.
Me - Yeah, your choice. Good luck with your new phone.
See where the problem lies. Lack of quality apps, lack of features, lack of high end and good mid end phones and the perception are holding Windows Phone back. One positive thing in favour of WP was its UI which is being scraped. People would adore Metro if it had apps. It's not the UI which is holding back. Don't try to fix which is not broken.
