Aside from integration in bing and whatnot the article states:
"It is reported that Microsoft’s investment includes a rather peculiar agreement. The organization would receive 75% of OpenAI’s income until it has recovered its initial investment."
I guess I'm not a believer in "Microsoft will make it so the Bing search engine returns a hybrid of ChatGPT answers + scraped web pages and therefore more people will use Bing instead of Google and therefore Bing ad revenue will go up"
