There is no ethical consumption under capitalism (never has been), and while it might make you feel a bit less shit for an instant, this effort you’re making isn’t going to have any actual impact (the companies don’t care about you, or their workers, they care about profit. All of them. And your personal spending is insignificant to them in that sense) and a much better use of your fight energy (which, as a fellow wheelchair user I know is probably already spread extremely thin) would be on addressing the system itself, not the symptoms of it which are pretty identical across the industry… Other curriers treat their staff just as poorly, they’re just not a big name so it’s not in the news.

Give yourself a break, pick your battles (E: much easier said than done, I know, but you still must, for your own wellbeing)
