Facebook unveiled its new Home family of apps earlier this week, with a strong focus on "people, not apps." Microsoft's head of corporate communications, Frank Shaw, has taken to the company's official blog to voice his issues with Facebook's presentation. Shaw jokingly notes he had to check his calendar a few times, not for April Fools, but "because the content of the presentation was remarkably similar to the launch event we did for Windows Phone two years ago."

Shaw takes issue with Facebook's idea of putting people first over apps, something that first debuted in Microsoft's original Windows Phone 7 announcement over three years ago. Shaw, who is regularly involved in Microsoft's battles against Google, digs at Android, noting it's "complicated enough without adding another skin built around another metaphor." He finishes his frustrations by noting that Microsoft applauds Facebook "for working to give some Android owners a taste of what a "people-centric" phone can be like," while suggesting people try "the real thing," a Windows Phone.

The frustrations are clear, but it's a surprising approach from Microsoft given its close ties to Facebook. Microsoft purchased a 1.6 percent stake in Facebook for $240 million back in 2007. The pair have since partnered on Bing social search and Facebook's tight integration into Windows Phone. However, The Verge understands that Microsoft has been lobbying Facebook to bring Instagram to Windows Phone, a process that has left the company and its close ally, Nokia, frustrated. Given Microsoft's numerous Android patent deals with hardware makers, it can't be easy to see Facebook, a close partner, launching a new set of apps exclusively on a rival platform.
