I get why they did it, but it feels like something is lost as a result.
There’s a chance it’s for the better.

In the book, Paul does everything he can to avoid the jihad he sees coming, because jihad = religious fanaticism = bad. A crusade is also religious fanaticism and is also bad, but portraying the term “crusade” as an evil to be avoided could be a good thing for an American audience. Crusades are a part of Christian culture, and if you’re going to write religious criticism there’s less of a risk of it being misinterpreted if you use the audience’s dominant religion as an example. If you criticize religious fanaticism using the religion of the Other, it’s easy to interpret that as nothing more than “Other bad.”
Plus, we’re almost guaranteed to get some Christian chuds throwing a fit over it, especially with the rise of right-wing “crusade” imagery. That’s always good for a laugh.
Spoilers for a book that came out half a century ago, I guess.
Is it really Islamophobia if you’re portraying a religious war as bad, and using a Christian word for a bad religious war instead of an Islamic one?
I thought the point is that the jihad - at least, the one that Paul tries to prevent - won’t, strictly speaking, be bad.

He ended up riding the jihad, steering it a bit, but it was never in his power to stop it. The Fremen were, from the beginning, going to cast the Harkonens from their world, and the jihad brought a new vitality to the Imperial apparatus.
Now that I’m writing this, the worm, the unstoppable creature that is the source of spice, I see that the worm is a pretty clear metaphor for the jihad.
