The problem with that list is it only shows the parent company.
Sara Lee, for example. I grew up eating Colonial bread. Sara Lee bought Colonial. OK. I can find another bread. They also own Jimmy Dean sausage, and that annoys me mightily, because I like Jimmy Dean sausage. I deprive myself of it, because it is owned by Sara Lee. If I did not know that Sara Lee owned Colonial and Jimmy Dean, I would continue to buy them, thus giving money to the enemy.
You can't just go off the list. You need to research particular products, to see who actually owns it. You can't even guess at this. I remember, several years back, either Holley Carburetor owned Colt, or Colt owned Holley Carburetor. I'm not sure which it was, but the two companies have absolutely nothing in common. But they had the same owner.
But it gives you something to work with. There are going to be situations where you don't have a choice but to feed the enemy. In the end, it's going to be each person's personal decision and priorities that will drive what they buy and don't.
Just like people still continue to buy Springfield Armory and Rock River Arms products or firearms from Turkey like Canik. It's their right and their money even if I don't agree with it.
