This seems to be a common position on the Left. It basically says, "I agree with the 9/11 Commission Report, but for unspecified reasons I feel there are unanswered questions."

It's a positive for 9/11 Truth, in the sense that it acknowledges the 9/11 Commission was a fraud. But it's maybe a little too confident in the official story (I'm not 100% certain of CD, but there is a very compelling prima facie case for it. So it's difficult to declare case closed in light of so many anomalies.)

As I've said before, the only "re-opening" of 9/11 I can see happening is an investigation into some tangential element of the crime (probably something to do with money), which then leads to wider implications for the 9/11 narrative. The entire 9/11 case will never be re-opened, but some portion of it may be.

So in that sense I think this article is a good thing.
