Not commenting on the truth, but the reality is many do not trust items from certain countries. If an AV from Russie has been banned, and drones from China are or are soon to be also, it makes sense these could be trade related only (bans bought by US competitors), based on fact/fear, or a little of both (likely).
I thought about buying a certain computer brand but skipped it because of the origin.
I happen to use a local hardware firewall and can ban and monitor all outgoing items. While I am fine with a global economy, it is an eye opener how many things we usually trust try to connect to places most would prefer not to. As a for instance, a game my spouse plays has to connect to a country I block (for ads) to function, so IU had to setup a safe path for her game to work!
