I think this decision is hasty and completely unjustified. Diabler played all his games and was resting calmly, while Cost didn't even bother and wasn't going to finish the tournament. Now, for some reason, he's going to get another point from Diabler. Or maybe everyone will get a point from him? Cost should be banned from the tournament because he wasn't going to play or finish any games. And now they're giving him this ridiculous point.

The decision is not hasty. I consulted with Pete about this. He has experience running tournaments and resolving similar situations.
Diabler played 4 out of 5 games and only The_ won against him. It's unfair to deprive him of such a good score.

Or maybe everyone will get a point from him?

Everyone else has already played and received points according to the reports.

Cost should be banned from the tournament because he wasn't going to play or finish any games.

Whether Cost was going to play a game with Diabler or not, we don't know. It's enough for Cost to show up and say: "I was actually going to play with Diabler, but he withdrew." We will deal with his other games after the deadline, according to the criteria that Pete mentioned above.
