But the observation you quoted, “Apps aren’t able to read the clipboard without you understanding about it, so you can make sure the contents of your clipboard are safe from unwarranted access”, quite actually is true. You will be informed when an app uses the clipboard, and you can choose what action to take. That action may be to remove said app and seek an choice. If you have chose to do not anything, then by your inaction, you have deemed the app’s access warranted, even though you don’t like what it’s doing.
Don’t conflate “I don’t have a decision” with “I don’t like the available selections”, they’re not an analogous thing.
