> What "national security" implications are there with VPNs?

"Foreign agents" communicating in an untraceable way.

All internet communication is wiretapped by default unless you use a VPN to a rival jurisdiction. (Where it's also wiretapped, but presumably the interplay of state actor interests comes up in the "foreign agent"'s favor.)

"National security" has long been their favorite cheat code for 'do what I say, you can't question it, damn it!'. The boy who cried wolf has nothing on the old man who cried national security.

Clearly, Big Government can't see what you or your company are doing and that's a problem for them.
