No, they were finding them, outing them and reporting them. As he says in the post. There were doing that work.

They're being sued by a victim for not preventing the victim from being manipulated by an abuser. The fact that the abuser was caught and convicted with Omegle's help is apparently irrelevant.

It's hard to see how Omegle could have done this differently; no crime occurred until the victim was abused, and once the abuse happened any subsequent action is irrelevant because the victim was still abused.

Roblox will have more ability to hire lawyers to win the victim's court case. That's the only difference.
