re: effects on sales
Just a gut feeling, but I suspect this will have little to no effect. At least in the long term. I know a few friends who love CFA's food, but have boycotted then for awhile out of disagreement on these very principles. I think the people who would be prone to boycott, pretty much already do so, because they are aware enough to know the company's owners hold these beliefs.
And that's the part that gets me about this controversy more than anything. The family has been open and honest for forever. They've never tried to hide anything. This isn't new news. Those who are conscientious enough to care already knew.
