I don't think there's any technical knowledge needed here; the concepts are common ones. "There was a big hoo-hah about how it used to output a certain well-known piece of code in possible violation of its licence. They fixed it by blocking any output that includes the name of that exact paragraph of code. In particular, it can still output other code from the same codebase with the same licence; just not that particular paragraph." The direct analogy would be trying to stop it from outputting The Lord of the Rings by blocking the phrase "a long-expected party" (the title of its first chapter).
