If magnetic accessories might interfere with iPhone cameras, how are the MagSafe products any different?

So basically what is says on the tin. I was about to buy a MagBak case and a wallet, but then I stumbled upon the Apple statement that says magnetic accessories might interfere with iPhone cameras. It was released on July, but now Apple has launched its own line of magnetic accessories in the form of the MagSafe products. Is there some specific reason why MagSafe will not ruin the camera, but, for example, MagBak might? Or is the iPhone 12 line just better protected?
