Tech companies and their executives have, broadly, moved to align themselves with investors and adopted a posture of, often, disdain or outright hostility towards their users and employees. If tech companies don't value you, why provide value to them? If they back political positions hostile to your interests, why not return that hostility?
People who lead by example while standing on business ten toes down and NOT self-deprecating?
Humility hurts more than helps in many situations, like here in this one. “I do all that but I humbly believe it’s pointless, it makes no difference.” That’s not the energy that gets things done or is appealing to watch or to join.
Assuming that enough people will come to a personal epiphany at the same time to make a difference hasn’t ever worked, though. There must be a catalyst if you don’t want individuals to do the right things years apart, ineffectually.
