It was not the choice of the creative team, and was effectively forced upon DLE by corporate (specifically legal), because they were afraid of a lawsuit due to "religious offense" from some non-Christian religious groups. Threats of several were made, and in 2013 they removed it because they felt the risk was no longer worth it. True story. Many (including some narrators) are still very angry about it begin removed to this day. Disney may have "had a word" with some of the more hardcore fans who narrate about not using their speaking slot to read the poem.
Fun fact - the poem was also the only time at UCF that I outright heard a religious text read aloud (or really even mentioned). 2nd time I got chills (the other 2, before and after, were seeing the Disney internal only video of Reflections of Earth, with a full flat view of the globe). It is just that good of a poem.
