It seems to me that it makes no sense to spend resources and money of Dice on supporting high jack pot, taking into account that the audience is growing even without it.
Jack pot has always been inalienable part of major casinos. Im sure that the platform team understands it well.
However, judging by the blog entry about the upcoming changes, I Dice is expected to see a lot of changes, and I thought that elimination of jack pot would help to reduce commissions.
