One can be forgiven for thinking that whatever threat Huawei might present to individual users is not much worse than a Google or a Facebook. But the thing that makes China different is the sheer scope of their effort; data gathering tasks (we'll be kind and not call it what it really is) are spread across the entirety of the Chinese infrastructure with specific elements focused on specific classes of data. Individuals, companies, military and the civil government are all involved. This is operation on a scale that makes even Google look like a bit player. Returning to Huawei in particular, the following was published by the Lexington Institute on their website a couple of hours ago. The subject was about Germany's support for their NATO obligations, but the comment stands on its own: "Turning to China for technology. Germany missed the boat on high-speed internet, so now it is trying to catch up. But despite warnings from Washington and other allied capitals, Berlin is signaling it will allow China’s state-influenced Huawei to play a major part in building out the country’s 5G mobile network. Chinese telecom companies are required by law to assist the state in pursuit of security objectives, and U.S. intelligence has long feared that Huawei equipment might be used to compromise Western security—for example by collecting sensitive information. By embracing Huawei, Berlin is legitimizing use of the suspect company’s technology in other European countries, potentially a big blow to alliance security" In the interests of full disclose, Lexington Institute lobbies for its clients (who are various companies who want to publicize articles that support their business interests), but this particular paragraph isn't scare tactics; there are enough security incidents and network hacks with China's fingerprints on them to make the above assessment credible.
