Moreso that participating in modern society is impossible without doing business with companies who have unsavory labor and environmental practices. I'm not commenting on morality.
Expecting some sort of change to come from spontaneous, collective consumer action is ridiculous. This is especially true when most consumers in America are not on financially stable ground themselves, and can't afford to spend more money or time to assuage their guilt.
That had more to do with fostering a workplace culture conducive to harassment and his opening of Uber to massive legal liability from Waymo. Uber's investors forced him out, not consumers. Investors have power because there are generally few of them and they have a great deal of skin in the game. Collective action is both easier and more incentivized in that case.
These things never start from the poorest doing these things though. They start with the middle and upper classes, because the do have the money, and companies chase that money.
