If you find yourself thinking "I'll surely be down voted for this" you could use the chance to ask yourself if what you want to say is worth saying and if it is, consider how you could get the worthwhile ideas across without being objectionable.

In this case, for example, it seems like you're partly upset by the author's race and gender. Judging people for that, or holding it against them, strikes me as objectionable.

You're right that not everyone has the opportunity to pick what they want to work on, but that's a rather trivial observation and not one really worth making in my view. If someone wrote about performance bicycles, would you scold them for worrying about such irrelevant machines while subsistence farmers struggled to eat, or people in Asia battled the coronavirus? Must all conversations and topics be about the people in the worst position?

Your comment, since you seem to want a reply and not just downvotes, is needlessly antagonistic and doesn't offer any useful insight. You complain about the race and gender of others, startups you don't like, hackernews, startups, and the idea of extracting value. Your core point is obvious to all readers.
