That is the same as saying "They should be contained because I'm scared, even though I have no proof." That, is called prejudice.



There is a lot of fear but no details, no facts, no knowledge. All you need is prejudice.



I also have a technical background, plus I have worked in the telecommunications industry as an engineer. Do you know how tough it is to build a piece of equipment that is functional, technically competitive and cost effective? If you do, you would know it is not feasible to also add into it snooping and recording features. This is not a plain old telephone. These are switches that process Gigabytes or Terabytes per second. How can they at the same time record the data, analyze it, and have the spare bandwidth to "report back to KGB"?



Even if you don't have any proof of the "evil" China, even if you are fearful of no longer being the most technologically advanced country, even if you are full of prejudice, at least you have basic logic, and know that most of the crazy claims just don't hold up to basic physics.



If the Chinese equipment were able to do deliver all the telecommunications functions and at the same time secretly do all the alleged snooping, China would have already completed "China 2025" and have overtaken the US technologically by 5 to 10 years.



Instead, the situation is more likely that Chinese companies are a few years behind the US ones. The difference is that they sell at cheap prices. As is often the case for underdogs, they have lower profit margins than the technical leaders.



If you say that there are likely still a lot of pirated Microsoft Office copies in China, I would say you're likely correct. But if you suddenly defy logic and make impossible claims like the Trump Nut Cases are doing, you stop making any sense.



No matter how much prejudice you have, it can only blind you for a time. Eventually facts and logic will bring you back to Earth. Claims that make no sense, have no proof, make no sense.
