I don't really understand why you think they're relevant, given that this conversation is about the training itself.
Even the news orgs say explicitly in the press releases that it's about training on their archive
eg. http://ap.org/media-center/press-releases/2023/ap-open-ai-ag...

Axel Springer https://openai.com/index/axel-springer-partnership
Stack Overflow: https://stackoverflow.co/partnerships
Disney (for characters in video. Video is especially where licensing is a big difference internationally right now) https://openai.com/index/disney-sora-agreement
etc.
The news corp one had a leaked price ($250mill), so they don't seem to be insignificant. These would have to be included in API prices I presume.
