Do Raspberries’ cause disease to Blackberries?

One of my friends here in Kentucky told me he planted his blackberries within 20 of his raspberries, and over a two year period it pretty much killed the blackberries do to some disease that is associated with the raspberry but which they are able fight off.

Any truth or experience with this?

I am quite sure they share some pests, even though I don’t know which of them would kill blackberries.
I have gall gnats on my blackberries which I haven‘t seen anywhere else, so that pretty sure came from my raspberries, but they don‘t kill either of them.
