It's a tough spot for them really. They obviously don't feel they have the resources to support the app. If they pull it from the store, the few customers who did use it will get mad it's not available. If they leave it in the store, the few customers who do use it will be complaining in 6 months that it hasn't been updated. In addition, as a company do you really want an official app and service floating around that you can't support? I don't blame them for pulling it.
