Earlier quoted context omitted.
You mean so you can snoop from the user without being detected?
There are a lot of valid usecases for clipboard saving, I don't have an iOS app but I run CopyClip which would be kinda ruined by this "feature".
I use a password manager on my iPhone and I am copying and pasting my passwords all the time. If some random app is scraping my clipboard silently and sending the data to a third party, that means my passwords are compromised. I am very much NOT OK WITH THIS.
Keep in mind, this permission should be fundamentally different than the permissions for just manually copying and pasting. I don't want to have to deal with permissions to "allow clipboard use" that I have to approve every time I want to paste something. That would be obnoxious. I am only worried about restricting permissions for invisible passive snooping.
