The real issue is that nothing has changed since a 2014 report from The Register that Huawei categorically refuses to install NSA backdoors into their hardware to allow unfettered intelligence access to the data that crosses their networks.
However, documents disclosed by Edward Snowden this year suggest Huawei may be more sinned against than sinner. The US National Security Agency’s ‘Tailored Access Operations’ unit broke into Huawei’s corporate servers, and by 2010 was reading corporate email and examining the source code used in Huawei’s products.
“We currently have good access and so much data that we don’t know what to do with it,” boasted one NSA briefing. The slides also disclose the NSA intended to plant its own backdoors in Huawei firmware.
