I don't know if it's just optics. As a user, I personally don't want to see or download apps that are broken, neglected, or completely left for dead. Maintained apps are usually the best ones right?
One example doesn't prove that statement false. I said usually.
But also I'm not sure that's a great example anyway because I'm sure most people would want to find Microsoft apps on the app store regardless of what you think about their "usability" or maintenance. Usability is a different metric that's more arbitrary
