Data networks are critical infrastructure for any state.
Civilians, businesses, and the military, all depend on them.

Now I understand why American firms would want to, because the bottom line rules all. Which is why the American government was also right to ban, or limit, Chinese telecom hardware, from a pure national security perspective.
Just as China would be right to do the same, given that they have the domestic manufacturing base to provide comparable domestic capabilities.
