Isn't that just the US speaking in order to get more control? How is it proven? I've never seen any evidence of that, but there has been much evidence that the US does what they blames others of doing, like this and Cisco.

At this point it seems the US is accusing others for doing bad things because that's what they themselves do.

Huawei was growing really fast, threatening both Apple and Google. Then the US said it was not safe while trying to sabotage both smart phone sales and mobile networks sales. The US pressured allied countries to not choose Huawei for 5G, and didn't let companies work with them.

Huawei was also willing to compromise by giving network operators acces to source code.

Is Huawei bad? I don't know, and I've yet to see any evidence. Does the US do exactly what they are accusing other for? Yes, that has been proven multiple times.

We live in a day where we talk about privacy and security, while giving large corporations full control over our iOS and Android devices. How useful is e.g. E2E encryption really when the os itself has a direct connection to the mothership?
