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.
But liberalism (both in the modern American sense, and in the classical sense of which both modern American liberalism and mainstream modern American conservatism are subsets) is a system which overtly valorizes greed and the pursuit of personal gain in a facially neutral common market-based environment as both a deontological good and a practical engine of social progress. (Modern American liberalism differs in its expression of this from the modern conservative expression of classical liberalism in favoring modest and limited active correction of the impact of past deviations from the ideal of facial neutrality as a matter of Justice and restoration of the ideal neutral condition whereas the conservative expression of classical liberalism favors studious current facial neutrality.)
