They don't want to piss off the Bomb Throwing Jihadis.
That's one thing.
It's entire another thing to say that they changed canon that simply didn't exist before they created it.
Jackson didn't do that. Very little of what was in those 3 movies wasn't part of the extensive canon with which he worked.
But that's not the case with Rings of Power series. They took canon and raped it on the altar of wokeness until it was comatose, then cried and protested about how Trumpy and MAGA the people protesting their bullshit were.
