Protocols like TLS and encryption is there because any physical network is untrusted. If you have sensitive data, use e2e encryption. And any sensitive data is most likely already using such scheme. Also today's routers and physical network has insane bandwidth. 100 to 400 Gbps networks, billions of packets per second, millions of flows. To sniff the physical network and gather specific useful data, such as a personal contact, some files, or a message, especially from encrypted steams, is a huge endeavor. you would need a large dedicated ASIC with Gigabytes of memory, storage and large power budget. And you need a team of people to work on the software and hardware of such system. And there is no way you can hide such endeavor. Huawei has foreign people in key executive position and in multiple countries. I don't think its possible for the company to keep people quiet on things if these people feel its wrong. If Huawei's attempt to sale networking gear is a secret campaign to sniff and spy on world's data, there is no way these people would not find signs of it and stayed quiet. This whole scrutiny on Huawei has been a long time, multiple years. If foreign employees saw anything internally they would have whistle-blown by now. Honestly, if you want to know what Huawei is really up to, you could get some high ranking foreign employees to check up on executive meetings and documents. Huawei also have customers and partners working closely with each other. They also allow third party's review their source code and products. Many times partners are saying there is no evidence of security issues. Frankly, if a bad actor wants to get access to secret data, its much more useful to hack OS, servers and databases.
