I can imagine knowing the apps someone uses might be a telling thing to someone looking for leverage on someone (who might not want to disclose what apps they use). Apps can expose your orientation, your lifestyle, your income level, your habits, and even where to look to find you (imagine you have an app for a gym, that narrows down the list of gyms to find you at and is better than nothing)

Politicians, law enforcement, high value targets, etc. A list of apps on their phone could totally be used against them and is better than no list of apps.
