I disagree. I believe the most difficult engineering problem in the world is changing human behavior and decision making at scale. Not behavior in terms of "tap the screen more often", but actually changing how we treat each other, how we treat the planet, consumption and consumerism versus preservation and reuse. To that end, this is engineering, and they are on the right side of history. Further, social activism as engineering is important. It's engineering behavior so we're more inclusive. Inclusivity is important because we need lots of perspectives on how to solve problems. The more perspectives we have, the better our solutions will be.
