Well, first off, there are quite a few threads in this forum about tournament advertisement wording or terminology. I do not have time look them up this morning, but there is a difference between money "guaranteed" (key word) or "money added" (based on X number of players).
For those interested, here's what Tony Chohan said on Facebook (edited with punctuation for clarity):
"I just got done speaking to Vivian, and whether it is a misprint or whatever, the tournament is based on 128 players. But an accident, there was somewhere else that says something different, so I'm going to not apologize. But I am going to say that she is trying to do her darndest to help with sport in the right direction. I will leave it at that. She's not a bad person; i's just mistakes happen. And it was the first go, and I hope that next year it will be even better."
