I don't see what's odd about the article title. It says they clarified the EULA. People misread the original as if it made a claim on content, so the new EULA clarifies that this is not the case.
It implies that an exclusion wasn't present before, which is true. The EULA previously did not include a claim on content, but people were misreading it that way. So, as a point of clarification, they changed it to explicitly exclude a claim on content.
I see how you are reading "excludes a claim on content" as meaning a claim on content was removed. But what it actually means is that an exclusion of a claim on content was added.
