Indy's brother said:
Why name-drop HF and SS? Well, to give his bashing of the movie (deservedly or otherwise) credibility, and eschew the same blame that he started off wearing like the emperor's new clothes.
I would think that Shia name-dropping false opinions of Harrison's would elicit a quick response decrying Shia's comments, but I could easily be completely wrong.
My opinion of this whole affair is that I never gave Shia much credibility, and continued to not give him much after merely reading the title of the article--I mean, this was the same guy who was lauding the film before it came out, obviously to give it some good press. What his true opinions are, then or now, are difficult to discern.
I have to admit I'm pleased that this article came out, though. If they don't realize it already, this article will make it clear to Spielberg and Lucas that their latest Indy film was perceived as a mixed bag (a generous description, in my opinion), and they should probably go in a different direction should they make Indy 5. It's kinda like Last Crusade being the apology for Temple of Doom, though to be honest I find Kingdom of the Crystal Skull to be closest to Last Crusade in tone, so . . . maybe the American audience wants a new Temple of Doom, sans annoying characters and possibly offensive dinner scenes.
