I think this is not correct and perhaps a deliberate downplay. The US Govt theoretically and in many cases provably has backdoors in the very fabric of the internet itself, and has tendrils in products of many of the companies and entities responsible for everything from transistor to application.
It is however, in the US govts interest to not present this, so as not to encourage people away from US tech.
