Thanks for pointing that out. The real ad appeared in the computer magazine Interface Age, September 1976 page 13, as can be seen in the Internet Archive. I think it's important for Hacker News to avoid fake/replica historical info so it doesn't end up like Reddit, where you can't trust anything.

The downfall of Reddit is so depressing to think about.
I trusted Reddit wholeheartedly in the 2010s. Redditors taught me the life advice I didn't learn growing up: how to shave, how to negotiate job offers, how to do things around the house, and so on. Huge subs aside, you could that every post you read had a human on the other side of it, and no-one wanted more than upvotes and Reddit Gold.
Once spez and crew decided to push the MAX GROWTH button, all of that flew out the window.
Now that LLMs make infinite content generation child's play and there are financial incentives for being a content provider, there's no going back. I'm doubtful that another service like that will exist ever again.
All that notwithstanding, I still search for stuff on Reddit because the rest of the Internet IS EVEN WORSE. SEO ruined websites, CPM ruined YouTube, and LLMs might not even tell you the truth! I wasn't expecting to start yelling at clouds in my late 30s, but I guess we're here now.
