Yeah Jackson even explained that in one of his interviews. Bombadil doesn’t really contribute anything to the main plot of the books or the character development of the hobbits. He’s a mysterious interlude that never appears again or has any effect on the plot development or outcome. It just wasn’t possible to justify giving him precious minutes in an already long movie, and would likely have confused audience who hadn’t read the book yet. But I’m also not aware of anyone who actually dislikes him, as the article asserts.
