Literally none. Where they vary is in how maliciously they'll engage with consumers for a quick buck, and within that spectrum some are definitely better than others, but every single one of them draws the line at profit.
I agree but to me some brands cross a line making then especially horrible. I don't generally boycott products because I would never be able to buy anything if I tried to stick with GOOD companies. But some are so bad I do avoid them.
Tesla
Walmart
Monsanto ( they were bought by Bayer)
Just to name a few of the top of my head. Obviously there is no shortage of truly terrible companies.
