Why not assume people are being genuine? Uber has done tons of things to piss people off. I think people in the HN bubble forget that the majority of the country has never been in a ride share. Talk to some blue collar people. Talk to some taxi drivers. Talk to drivers who left Uber. You might find that they aren't as sympathetic to Kalanick as people on HN are. HN in general has more sympathy for corporations and billionaires than I've seen anywhere else on the internet.
I'm not sure I have good recommendations, I spend most of my time reading things on here since I quit reddit. My last sentence is tangential to the main point of my post, which is that Uber has earned all of it's scandals through their actions. This Greyball project is astounding, and it's no wonder that someone eventually leaked to the press about it.
The point I was making about internet comments is that comments on HN are particularly sympathetic to start ups, entrepreneurs and corporations (obviously).
