I think we're in a much better position to change the culture at Google by having a discussion here on HN than Google is to improve the Palestine/Israel situation by making a statement.

I would even say it's a noteworthy possibility, given that many people who are or will be influential at Google read HN.

But the distinction here about having a discussion vs. making a demand is also relevant. When someone is demanding you make a statement for seemingly no purpose, the real purpose is to assert control over you.
