Best way to avoid this is to buy in official shops with cash, or make make your own signing device.

Buying in official shops with cash might not be possible in the area where a customer lives. And it doesn't fix the problem when you register for a newsletter later.

Everyone should use a unique and unrelated email address from your usual identity for such newsletters or services. This might mitigate a little such data breaches.

So far, I went the route to create my own signing device, mainly because I'm not too happy with what commercial hardware wallets offer or cost and I don't feel the urge to need a commercial device yet.
