I'll just say a few things in the end, because I got a refraction due to my earlier post.
I'm not trying to undermine Microsoft or it's services, I am simply trying to say that Windows Phone needs Google services, primarily because Bing does not provide the same level of global coverage that Google does.
Having used a Windows Phone for over eight months, there was no good navigation application for Pakistan(HERE and Bing didn't support it either).
Not to mention the fact that Micrsoft applications and services have a negative reputation all over the world, from Internet Explorer to Bing and so on.
You could have the argument about Microsoft vs Google services all day long, however you can't deny that most people prefer Google over Microsoft and need their necessary Google apps regardless of the platform they are on.
Moving on, Microsoft and Google both collect pretty much the same amount of data from you but both explain why they do it, they don't sell your data or anything. But if you have reasoned criticism against Google's privacy, please comment on this thread on Android Central:

That's all I wanted to say, Windows Phone does indeed need Google services.
