I guess the point is Google says windows phone is not big enough or us to build apps for. Now they say they are big enough to hurt YouTube creators revenue. Google essentially is lying somewhere which is wrong.
Microsoft should not steal revenue from the content creators. However for google to call this out it means that Windows phone is material therefor they probably deserve a first party app from Google.
I hope they unveil an entirely new device for all carriers that would be impressive. They still do not have a $200 phone in the US and that might be something Nokia is looking to fill.
