After Twilio filed for IPO, someone wrote a "here's what Hacker News said about Twilio," which only focused on the hilarious-in-hindsight but negative comments about the startup (https://news.ycombinator.com/item?id=11786464). Naturally, it got massive retweets from venture capitalists who espouse the haters-gonna-hate attitude.
As dang notes in that other comment thread, this kind of argument doesn't look at the other side at all: there have been some seriously shady dealings going on with unicorn startups. IPOs are failing. And let's not get started on Theranos.
