Playing the devil's advocate: Removing bonuses while leaving the instant busts unchanged, thereby more than quadrupling the effective house edge, would likely not be received well by bustabit's player base. The site operator knows the game results in advance and also every player's wager size. He could use this information advantage to skim off the top of the bonus pool, which would largely go unnoticed by players.

However, I fully agree with you. Ryan has operated bustabit without any incidents since he purchased it two years ago and has never given any cause for distrust.
