I'd say the very fact that you have to read into the detailed post to understand which "black" is indicated in the title supports my claim that the term is problematically overloaded.

You are expected to read the posts on HN before commenting. It's one of the norms of the site. This isn't a newspaper article; it's a post they wrote specifically for us, in our norms. You should not feel good about trying to litigate this at their expense.

We're here to talk about the startup they're launching, not about this. Again, I don't think you should feel good about trying to score points like this.
