I think the sooner the west (read US/Canada and Europe, some say Australia/NZ) realized and wake up from their denial the better. Gone are the days of the narrative we're not going to export to you our superior and more expensive products, but now the narrative we're not going to import your superior and cheaper products, how the table are turning 180 degree. It's not uncommon to watch western Youtubers praising the good quality DJI products and at the same being critical of GoPro sub-par quality products, and they're not even reviewing the products but just honest remarks from professional users going about their filming and recording routines.
The issue is even bigger than that. It doesn't matter what the device does now, nor does it matter whether it is open or proprietary.
When it comes to national security, ask yourself "what could happen in a time of war?" Some obvious answers are:
1. If it connects to foreign service providers, those services could be shut off or changed to be malicious
2. If the device uses parts/support/updates from foreign service providers, those could be discontinued, or changed to be malicious
3. If you need the product, but don't make them locally, they may no longer be available.
etc.
It is a national security concern. Whether the cure is better than the poison only time will tell.
It reminds me.. when someone is cheating on a partner, they are more likely to think they are being cheated on too. I have experienced this, being accused non-stop when actually they were the one cheating all along.
Just because USA likes tampering with proprietary code and using NDA’s with Silicon Valley to bug just about anything they want (because they can), that paranoia consumes them that other countries are doing the same.
During times of war, other countries absolutely do the same.
Just looks at the western reactions about 'foreign agents' bill in Georgia.
But obviously an existential crisis is not the time that many governments stand on their principles, which is why 'war powers' tend to be justified under extenuating circumstances when countries end up at war.
There is no question, if there is another major war between world powers, they will invoke the authority to compel their industries to cooperate with the effort. If they don't, they'll quickly cease to exist.
