I haven't heard anything about this. It certainly sounds like FUD.
That is what I am thinking, but it never hurts to ask the community experts.

It's not FUD. You should upgrade from insecure addresses to modern adresses. Just like you should update your operating system to the newest version to fix security holes.
It's unfortunate but we should have never sold this idea of "forever" addresses. Idk where this idea came from in the first place, certainly not from people with a cs degree.
Even for the most optimistic people: it's foolish to think that cryptography from 20y ago is insecure but current cryptography will still be secure in 50y. Given history that would be a surprising future.

I think it is a bit of both. Updating doesnt always make it more secure.
