The Windows Store has been stuffed full of fake apps trading off the names of other, genuine big-name apps with various levels of malicious content for years. It's definitely rent-seeking, and not in any way a "secure and trusted platform".
Your proving my point. When the store was first launched it did have a problem with misleading apps. But today those problems are far less. MS tweaked their submission policies and tossed the misleading app. That shows continued work on the trust and security of the store, a value add, and thus not rent-seeking.
