Well, technically there are a shit ton of shitty subsidiaries. There are only like six companies, period. Which is a problem in and of itself. And it turns out all six are shitty.
To be honest, it's not so much shitty companies, but shitty purchasing decisions
I wouldn't buy any products from any brands listed there because I know they're cheap, over-processed junk. Literally everything there.
If you're buying that stuff because it's cheaper, you need to learn about nutrition. You can get far more calories/nutrients/minerals/protein from slightly more expensive products, costing you less overall
...? Did you even look at the picture? That's 60-70%+ of the brands in any major retailer. It a bit of an oversight to suggest that poor decision making is leading to buying from these shit companies. You have to actually go out of your way to NOT buy one of these brands.

I'm still on the buycott for Kelloggs after they dropped breittbart so all I buy is special k. Unless they've changed something since then.
Edit. Looking it up, looks like they were doing alrightish but then they busted a union. On the other hand Post is working with trump, and general mills has been working with Israeli settlements. I guess you can go with some small brands. I'll still buy Kelloggs until I hear they change paths on breitbart since it's what I'd been doing.
