This has nothing to do with Microsoft.

Due to anti-trust law, Microsoft can't have any influence over decisions Nokia makes before the acquisition[1]. Even if Microsoft hated the idea of Nokia building and Android phone (likely) it could do nothing about it. And, even more importantly, Nokia could NOT change its plans even if Microsoft wanted them to.
