I just read over on Google Ad Developer Blog that Google wants your money from placing ads in developers apps on WP8 but at the same time refuses to support Google Services like Youtube. Wow Google must be hurting since Microsoft gets paid royalties for every Android Device made. Google has another think coming if developers will use their money grubbing ad service but refuse WP8 Google services. Are you a developer? If you are, would you use this money grubbing service?
