"probably"
"most likely"
yeah, we're being real clear.
Here's what I think "probably" happened: Obsidian told the backer to submit a new poem. Since he's willing to donate $500 to the project, he probably doesn't want to cause trouble for Obsidian and caved and submitted the poem you see in the OP.
The fact the backer made a new poem means nothing, the original should never have been taken out. He should never have been asked to change his poem.
