Well, it's not just tech; it's any large corporation that gets coverage. Some people can only hear "we're making the world better" so much when by all appearances they are just making their own world better. I know it's not a fair assumption to make, but look at what gets reported (billion dollar companies that produce nothing with no profits, high level executives greatly rewarded for failure, and so on) versus the unknown companies that actually are trying to make things better with no coverage.
Certainly. But this is about information. There are a lot of people who increasingly understand the dynamics of how the information economy affects popular opinion, how it affects the workforce, how it has disrupted work and yet done nothing to solve the problems that came with the consequences of that disruption.
And many on the left outside of the valley bubble really thought that a boom in the left-leaning Bay Area meant that there were powerful people there who had their backs in all of this. They feel very hurt that tech seemed to sit on the sidelines through the election, and in some regards pretty much enabled and profited off the mass-dissemination of misinformation.
So it's not just about corporate greed this time. It's about information, disruption, workforce automation, and the responsibilities that come from building and wielding powerful information tools.
