This sort of argument is something that annoys me incredibly. There isn't a simple answer. Responsibility is shared between the shareholders for failing to demand action, the board for failing to act, the customers for supporting a climate-unfriendly company, and the government for failing to regulate well enough, and probably many others. The result is the action of a system that has complex interlinked parts. You can't just point a finger and say "no, it's their fault" and absolve all the other parties. This is a major part of why climate change is a problem - no single party can solve it without action from the rest, and most of the parties have antagonistic goals.

If you're intelligent enough to read and comment on HN, you should be capable of thinking about things in a more nuanced way.
