The earlier generation of tech leaders were just as bad as the current ones. Bill Gates was willing to do almost anything to hold onto his near monopoly and to squeeze as much money out of it as possible. Larry Ellison has made a life’s work out of taking over software projects that benefited everyone, then brutally killing them. I actually met Steve Jobs several times and he was an awful person who made his fortune by exploiting more talented people. And so on.

There were plenty of decent tech innovators, as there are now. Then, as now, they did not end up running huge corporations.

I’m sure there were others, but the only exceptions I can think of were from the generation before that. Bill Hewlett and David Packard founded HP and made it a great place to work, a center of innovation, and a very profitable company, until they retired. And it all went to hell rather quickly.
