If Helldivers is anything to go by all they need to do is say sorry and that they'll do something on twitter and everyone will forgive and forget even if they don't do anything.
Until players start learning their lesson and not trusting these companies in the first place nothing will change. They admitted this was over sales of the upcoming black ops and it's multiplayer.
There was a 'game' about a cube that you tapped to get to the center wondering what was inside. If I recall each install only had a few taps. Only the person to finally open it would get the prize.
The prize was supposed to be the opportunity to make a game with him and all of the profits of something, then it became just a game he would make and like $1000000, then he basically ghosted the winner without paying him. He made a shitty beta half-game thing after like 8 years, then finally just said it was done without actually making anything really playable or even charging for it.
There's viddocs on YouTube about it.
