I see them using electric guitars, which are either being powered by generators that are run by fuel from big oil, or power from Portland Electric. I doubt they would have enough solar panels to run their equipment. They would have more credence if they were using non-electric acoustic guitars. Probably more credence if they were all wearing clothing which they made from stuff that they grew. It’s amazing how much we rely on these evil corporations.
