My local Costco is clean outta Rao's Marinara Sauce. Apparently there was a run on them because people are afraid the company's new owners will not only ruin the sauce but that they'll ruin it before the month is out.
Here's the thing though: Yes, it's possible that the new owners will make some fatal change in the product. But it has also always been possible that the old owners could do that; that someone high up in that company would suddenly say, "Hey, I've got an idea that would save us a lot of money!" Or that someone within that company who always thought the product needed High Fructose Corn Syrup would abruptly be promoted into a position of power and get his way. Rao's could also suddenly not be able to get their chosen kind of tomatoes or their preferred olive oil from their supplier.
I've worked with a lot of companies that ruined their businesses without a change of ownership. I think it's good to let the Campbells Corporation know that a lot of us love Rao's sauce just the way it is and are wary of it being changed…but let's not pretend that it would surely have stayed pristine if it had stayed with the old proprietors. Maybe the new owners now have a special incentive to not tamper with it.
