This is really the key. We’re all stupid and unaware of how things work and the particular goings-ons when we’re kids. There were plenty of shitty people running the tech giant companies back then, but we just didn’t realize the extent of what was happening.
Edit: The evolution of social media also adds a lot to this. We are both more connected to each other and society, and therefore more aware of BS think it’s pulled by corporations. Then, of course, you have folks like Elon Musk who seem to make a point of making sure everyone knows how big of a piece of shit they are, and how proud of it they are.
