To be very cynical, HN isn’t a nonprofit we all donate to either: it’s the wholly funded pet project of an organization who teaches growth and engagement (and in fact from what I hear is quite strict with its companies on expected monthly growth rate)
That HN is a thoughtful garden unconcerned with the ugliness of ads and growth targets is also unsurprising to me, in the same way that a lot of open source and other charitable giving comes from companies who are already comfortably profitable.
