Very interesting that the chatbot is taking existing content and spinning it.

I can see content creators starting to block this using the robots.txt part of their website, where they can block named bots from crawling their content. Presumably if you just block the Bing crawler, you block their chatbot too (of course that means your site won't get listed in the Bing search results, but if you don't get much traffic from Bing, it doesn't matter).
