Even ignoring how incredibly incorrect this statement is with regard to everything from countries sponsoring terrorism to countries enforcing extreme censorship on their citizens, this claim is pretty ignorant. You may be surprised to find out, for example, that Huawei was caught putting backdoors in its own routers (a far cry from Cisco’s packages being intercepted mid-transit), or that Kaspersky was caught scanning computers for classified documents.
If you want to convey that you’re concerned about US government invasion of privacy, that’s fine, and there are valid points to be made there. But don’t pretend like the US is even close to the worst offender in this area.
