I have not shared my Apple ID with anyone. I'm making the argument on behalf of those who have used Apple's own instructions for allowing them to share their purchases with others in their household. That's the purchase itself, not a readily available history of everything I have downloaded both before and after I shared my ID with them.
If I wanted to "clean up" my apps, music, movies, whatever, with someone before sharing my account with them, that is no longer possible, because everything you have ever downloaded is right there.
Furthermore, since you blatantly ignored my question the first time, I will pose it again.
If Apple had released iCloud with the ability to remove past purchases from the list, would you have complained about that?
Not from Apple's back end purchase history, because I understand the importance of them keeping a purchase record. But from what is displayed on the end user's purchase history.
