A specific incident, yes. Whether it's a small subsidiary or not probably is a red herring, unless there's something unexpected about that small subsidiary being involved in such a thing.

Really, though, this is just about avoiding repetition. The first principle of HN is curiosity. Everything else follows from that (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). Curiosity withers under repetition (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...). Generic discussions are bad because they're repetitive. There's a close relationship between genericness and repetition: generic is what you get when you take a bunch of things that have been seen and heard before, and blend them in a blender.

When a topic has been repeated enough to become generic, SNI is our only friend (see link upthread). That's basically the same as your specific incident. By the way, these specific incidents quickly become generic in their own right. An ongoing example:

Edit - by the way, it has taken years to hammer out these principles to the point that they've become building blocks of moderation that can be linked to and expressed in clear, concrete ways. I think it's probably time to collect this material into a more orderly form.
