Much of the general public isn't hip to the reality that their "favorite brands" engage in unethical and abusive practices. They're either unaware or willing to give them a free pass, because "they like them".

This has changed a bit with the backlash against amazon, but hasn't gone far enough. Lots of people are unable to look past the convenience to them personally. You saw this with Walmart: "they have great prices, and I can get everything cheaply in one place". I have friends with extremely progressive views on employment that love Musk and Tesla.
