Oh damn really good point. I was thinking the same as OP until your comment. Rebels definitely dove into this aspect in a very similar way like the Fremen. Andor hinted at it as well. Both explore what life is like for the everyday inhabitants of the galaxy, which is why they're so cool.

Although Dune was certainly more deliberate with making the indigenous people rising as a core part of the main story. Haha the Jihad was also a significantly different response than the Rebellion though.
