Large SV companies have nowadays become cash-making media machines of a gargantuan scale, acquiring that cash from all over the world for a service of questionable value, and investing it back in a relatively small area while providing only a few tens of thousands of jobs there. This distribution of capital creates a huge imbalance, no matter how "liberal" the stakeholders are.
My sense from reading was that he was upset by what he perceived to be hypocrisy on the part of the wealthy. In that they talked the talk about charity and making the world better, but their actions spoke differently. So liberal words, liberal values being expressed, but pure greed when it mattered.
What they do instead is that they boost their PR image and invest it in the "next big thing" like driverless cars, augmented reality, etc., and these endeavours often fail in a few years time, effectively wasting the capital and disproportionally enriching the selected few.
