It is very time consuming, tiring and takes effort to do principled shopping. For most people, convenience and price are more important than principles. I can’t think of many (any?) big companies that I’d be happy to give my money to, they all behave badly - only question is the degree to which each one behaves badly.

This isn’t complaining, just pointing out the reality - we actually don’t have as many options as we think we do. If one has extra money, they can spend a little more and shop at smaller but expensive places, most people are going to shop at Walmart or Amazon
