What, let a company supply a substance to intentionally harm people so they can sell them a cure?<p>I can see that going down well in other industries. The automobile industry can engineer metal fatigue into their axle joints and sell you replacements. Microsoft can build bugs into Windows and sell you critical updates to fix the flaw. Chair makers can sell you chairs with legs attached by screws that are slightly too short so they can sell you more screws of the correct size to allow you to remain safely seated...<p>I guess it would stimulate the economy.
