I agree, but the problem is that I don't necessarily think that Microsoft should be the police agency to enforce IP rights. Just one example of why is take an app that isn't developed by the IP owner, but the developer may have approached the IP owner and worked with them on development, and has permission to use the IP involved. Microsoft isn't a party to that agreement, and really shouldn't be, since they are just the proprietor of the store where the goods are being sold. That puts the burden of enforcing IP rights on the owner of the IP. Yes, that's a daunting task, and I wouldn't want to have to monitor all of the possible outlets where rights can be infringed, but with the help of people like us in the community, those IP owners can be notified of possible violations, and they can choose whether to send a C&D or not.
