Maybe he thinks it's too early to get sued over a blog-- he's only just got to the HN frontpage for the first time this year?
Subtext of his previous blogpost:
Capitalism is powered by greed.

EDIT: another post of his that got traction ~5 yrs ago was about the Swiss political system (Swiss are a pragmatic culture though afaik he's Slovak so we might have to account for some Iron Curtain baggage)
Maybe he quit google after 6 months, I don't know. It's easy to talk about greedy capitalism once you've made it. It's a bit harder to live by these kind of ideals for the whole duration of your career.
