Software developers make or break a platform, as Microsoft's Steve Ballmer once famously stressed, but that shiny new Windows Phone 7 site has angered a mildly important one. Rovio Mobile, developer of the wildly popular Angry Birds game, tweets that it's presently 'not committed' to bring the game to Windows Phone, and that the above icon is being used in Microsoft marketing completely without permission. While it's possible this is just some sort of mix-up and Rovio just wanted to make its own announcement ("nothing to do with if we do or don't, it's just that we decide that ourselves," the company added in a later tweet), it wouldn't be the first time Microsoft's engaged in shady business to inflate its new app store.

Update: Microsoft sent TechFlash the following statement: "It appears information was mistakenly posted to Microsoft's website, and has been removed." Sure enough, the offending logo is gone now.
