Like the way your irony works? I listed my arguments as why you can make a case that they are national security threats. You are more than welcome to call it a fake pretense but the fact remains that the majority of Chinese imports are not restricted and that includes tech/high-tech related items. If you have nothing more than America is ironic I can see where your endless questions stem from.
You obviously have a bias here so its going to be impossible to have any real discussion. There are very simple facts that I will restate for you. The CCP has seats at every major mainland corporation. Chinese corporations have in recent years been caught in some very spy like espionage, this is happening globally. China is an adversary to the US and Europe. There is no further burden of proof needed when talking about sensitive industries. You don't need to catch DJI in the act, similar to TikTok, if you cannot sever data/ties with the mainland there are real risks. Geopolitics suck but its a real risk that has to be snipped before it becomes a problem.
Do the five eyes and other countries have national intelligence that are collecting data, absolutely. I cannot recall any recent published articles about overt Western corporate espionage and especially any that were supported by a parent country.

And this is just one known case of the US spying on allies.
The burden of proof lies on the accuser. If you are not able to provide a proof of national security threat from tiktok or dji, then don't treat it like it's a fact. All the "ifs" don't constitute as a proof.
