Online slots are hard to control for gamblers. Faulty implementations (due to either wilful wrongdoing or contributory negligence) may result in the case described by OP. Physical fruit machines placed inside land based casinos have more credit in this respect and is why I play their more than often. However the fact that Draftking compensated those gamblers who were involved into reported spins is worthy of my respect.
To be honest, they were caught already, and so they will have to pay everything, otherwise there could impact their business and those players brought the case. Although I think that it could have been settled outside of the court and pay those players and make the issue quiet. But I guess DraftKing has no choice though but to face and admit to the faulty settings that's why no players have won.
This is the gambling industry, and for me, I wouldn't put the word respect though in one sentence with this casinos as their business is making profits of out us. If there is something that we could have to look at this case is that it could have been happening for many years and casinos profiting big, but if DraftKing is not caught, for sure this is going to continue.
