Overblown or not it's still better to err on the side of caution.

I don't trust corporations at all. Corporations will kill you for money. Some even specialize in it (Lockheed, General Dynamics, Boeing, Northrop).

Others just because it's inconvenient or costly to change, like GM ignition switches, gas tanks in GM pickup trucks or Ford's Pinto. Dupont's Teflon (which is basically made from fluoride). Asbestos.

One can take worrying about this too far, but ignoring known risks can be risky and so can the risks you don't know about.
