Big "How much can a banana cost, $10?" energy here.
We're talking about one of the cheapest brands of commodity pasta here. Think about how much effort you are implying the company put into this versus what 8g of major wholesale flour costs -- the only cost they'd really be saving in this conspiracy.
Even at consumer retail prices that's, what, $0.012 per box? And I bet wholesale prices are at least an order of magnitude less than that. Is the maybe tenth of a percent of cost savings worth a potential class action lawsuit and the horrific pain of Discovery that comes with it? And does that maybe tenth a percent of cost savings even come close to covering all the additional production costs involved in having that machinery calibrated so much more precisely? The juice is not worth the squeeze, my friend.
You think you're arguing that they would do evil for profit's sake, but you're actually arguing they would do evil for evil's sake even at the expense of profit.
