First of all, it's about an entrepreneur traveling to the US for a startup, which is directly relevant to a significant proportion of YCombinator founders themselves.
Beyond its direct relevance to the core founding audience of HN, it is not clickbait or wantonly inflammatory, and is clearly of interest to many based on the comment activity and votes.
Despite that there has been a general interest in "tech" and clever things and intelligent discussion here that appeals to a reasonably broad community so the place works.
The massive wealth concentration and power amongst a very few, the Paypal mafia, Andreeson etc has led them down a path that puts them at odds with the rest of us. Regardless of our diverse politics regular engineers aren't going to have more individual or economic freedom in a world controlled by a small group of oligarchs. They care about us about as much as we care about ants.
I wouldn't say the tech world has blessed the regime but many unquestionably revere the financiers of the tech world. We (techies) for all our talk of individual liberties have a problem with cult like thinking. Most of us aren't stupid and we can justify our positions, any position. And while some flagging of discussions might be sock puppets or bots, the truth is a lot of people still thoroughly believe the hype.
