My theory is that companies are not the sum of their employees. Employees are generally good; toxic humans are a small minority (unfortunately they tend to be over-represented at the head of companies).

But put employees together into a profit-maximisation machine, and the machine will try to maximise profit, with dark patterns and downright evil things.

Similar with our species as a whole: nobody is actively working to break the climate so much that their kids will die long before they reach the age of retirement. But that's what we as a species are doing together, somehow. Individually, we don't want that, but that's not enough.
