Apps using your clipboard in iOS 14

Another day, another warning for apps that use your clipboard. I trust Apollo but wonder why they are taking my clipboard at all. I think there’s info here that needs to be shared by the development community as to why they are using our clipboard. For me it’s a lack of understanding so I’m not targeting any developers, just want to know why in general for any app that shows this message.

Anyone else on the beta finding they are suddenly aware of their data being shared between apps?
