There is a very big difference between blocking the public (both consumers and business) from dealing with companies from someplace, and blocking companies from that place from getting access to critical infrastructure.

Especially if said company is controlled by its government.

Especially if said company has been caught using said kind of access to spy for its owner government before.

Especially if said country has made a reputation of systematically stealing all the tech and spying any way it could on you to use it "against" you.

Especially if said country is not part of the same geopolitical block as you.

Especially if said government does the same thing to your own companies in the same field.

Confusing regular commercial dealing and critical infrastructure deal and acting like they have the same security need or that one leads to another makes no sense to me, so your comment is, in my opinion, out of line.
