Because it's generic CHINA BAD FUD without much substance. GCHQ, the UK's equivalent to the NSA, did a review of Huawei networking hardware and found it is's as insecure as equivalents from Cisco and Juniper.

Instead of focusing on the actual stuff like the concentration camps or abusive work practices or neoimperialism.
