If I'm reading the clipboard part right, and seems people on the forms are thinking the same;

If an app can only access clipboard content that it set, does that mean we can't copy/paste between apps? That would be ridiculous. Does the act of pressing "paste" over right the block, and GrapheneOS will only block the background access apps have?

I like IOS approach, where it asks you before pasting "this app is trying to copy from another app", and you can allow or decline it. But it is really annoying sometimes.
