Unfortunately, that doesn't really prevent companies from doing things being illegal if they turn out to be profitable enough. You could use a multispectral hidden camera and an mmwave radar fed into 'AI' to simulate a lie detector - you can definitely get pulse and breathing rate out of it, probably also perspiration..

Sure. And then someone who set that up will get fired and leak the scheme, and nudes from mmWave will be found, and it’s all lawyers and liability.
