People do. I do, for instance. My blog is self-hosted, entirely human-written, and it is done for the sake of enjoyment. It doesn't cost much to host. An entirely static site generator would actually be free, but I don't mind paying the 55¢/kWh and the $60/month ISP fee to host it.
That only begs the question of how to verify what content is AI-free. Was this comment generated by a human? IIRC, one of the big AI startups (OpenAI?) used HN as a proving ground--a sort of Turning Test platform--for years.
