Well, in USA private companies do that all the time too bcs of the grip of the two-party system on private companies, eg it seems authorities have seamless access to Ring cameras.

I think that sort of thing is a given and part of your regular country risk. In most big countries it’s just a question how much the gov runs companies or the other way around.

But regulation can help a lot.
Eg EU could mandate a physical switch for wireless data (ie manufacturer) in cars.

… or you know, even mandatory foss or you-own-the-product-you-buy laws.
