No it doesn't mean that. What it means is that you, as a non-doctor, should excercise some discretion and humility wen choosing your words. Expressing harsh condemnation and judgment when you have a small piece of the picture is an unbelievable asshole move. None of these Tough Guys throwing around words like "crapware" and "spammer" would ever call anyone out like this in public, I guarantee it -- it's all keyboard courage and nerdrage.
This seems to be largely because they appear as a company that has strong driving principles about the sort of changes they want to see in the world.
IMO it's more due to the fact that YC asks for nerds to come as they are -- the entry process asks you how you're a hacker, and if you're selected you get an interview where pg wants you to geek out with him about your product. No flashy pitches or navigating social networks to get the right intro -- it's a process that cuts out all the BS that doesn't appeal to nerds.
The idea that there is some violated goodwill is just backwards rationalization. And it doesn't change my point, which is, essentially: who are you to question where YC invests?
