The only thing that would have stopped this attack would be to generate your seed off the device. And then, since the device is counterfeit and there may very well be a way to exfiltrate seeds from it, to use a genuine device, but that's a different attack.
What youre saying though is a good idea, provided the device youre running this on (and therefore entering your seed into) is secure. Since this cannot really be guaranteed it is often advised to never enter your seed into a computer, for good reason.
