I doubt OpenAI would buy the data, they probably scraped it already.

Looks like CGTalk was running VBulletin until 2018, when they switched to Discourse. Discourse is a huge step down in terms of usability and polish, but I can understand why they potentially did that. VBulletin gets expensive to upgrade, and is a big modular system like wordpress, so you have to keep it patched or you will likely get hacked.

Bottom-line is running a forum in 2024 requires serious commitment.
