I do agree with you! It's not a FUD they are trying to create. It's more of an official statement that says - "if the Bitcoins that we hold for you, get stolen due to the advancement of quantum computing, you can't hold me responsible and can't expect me to refund you".
It's a technique big corporations use to safeguard themselves in case anything goes wrong. I can assure you that this statement will soon become a part of their T&Cs, if not added already.
Exactly what I'm thinking as well, they are just trying to safeguard nothing more.
As for the quantum computing risk, it's all still speculation, none of quantum computer are functional enough to break the encryption at least until few decades.
But the solution is coming up, bitcoin isn't stagnating, it will upgrade its security and respond to such threat.
