The concern is that even encrypted communicatons, intercepted via the heavily Chinese-tapped US telecommunications company networks, can be used to gain access to other systems. Unencrypted data, sure, that's a legit concern. China can likely read every SMS sent to any US phone number and no one seems to care at all. Things like downgrade attacks, other man-in-the-middle attacks, and skimming SMS 2FA codes are likely possible with poorly defended systems.
If the data it's encrypted, then it's more about the paranoia that China is collecting everything and planning to decrypt later with quantum processors. Not exactly a huge and urgent worry, but one day they will crack how to decrypt what they collect and will have a record of everything said online.
