This is good news for all app users as it's frustrating to download an app to find it's not what it was billed to be.

Every app store finds its own balance between app quality and choice, which in turn opens the door to people trying to game the system with misleading titles or descriptions. Our approach has long been to create and enforce strong but transparent policies to govern our certification and store experience. Earlier this year we heard loud and clear that people were finding it more difficult to find the apps they were searching for; often having to sort through lists of apps with confusing or misleading titles. We took the feedback seriously and modified the Windows Store app certification requirements as a first step toward better ensuring that apps are named and described in a way that doesn’t misrepresent their purpose. These changes included:

Naming – to clearly and accurately reflect the functionality of the app.
Categories – to ensure apps are categorized according to the app function and purpose.
Icons – must be differentiated to avoid being mistaken with others.

These revised policies are being applied to all new app submissions and existing app updates for both the Windows and Windows Phone Store. We’ve also been working on titles already in the catalog, conducting a review of Windows Store to identify titles that do not comply with our modified certification requirements. This process is continuing as we work to be as thorough and transparent as possible in our review.Microsoft Moves to Stop Misleading Apps In Windows Store [blogs.windows.com]
