Re: I'm baffled
Well, it's not as simple as that because you may not always use the standard edit controls. In an app that implements a different edit box with different features, say for an actual word processor, you may want to be able to paste into your new area. Apple saw this need and implemented your basic clipboard where you could read at any time. Logically, they could easily have asked the user about whether the app was intended to be reading the clipboard, implemented rate limits, or various other security patches, but they didn't do that. Maybe their IOS 14 changes will include one or more of those preventative patches in addition to the retroactive warning mentioned.
