Well my call is that they had 0 legal council when announcing to publish the source code. Its no conspiracy theory, its more like a fact.
If another project runs on their source code they can be civilly accountable for the damage blizzard takes. In order for blizzard to sue viper/daemon they need their identity. Now lets say they have their identity.. Viper/daemon are done with their life.
Lets assume they dont have it so they have nobody to sue. What would have kept viper/daemon from hosting nostalrius themselves again instead of publishing the code? Just move to a country without this concept of copyrigjt law.. Like russia. And get a host that doesnt even require your personality, they would be safer than ever.
I think you got me wrong. Of course i praise the team as much as you do

.
Edit: fact is way over the top ofc.. Rather 'how i.interprete the case'. Tldr: the legal position for viper/daemon is the same, if they wanted to publish the code or launch thenselves again. If they arent in the legal position to launch again then they cant publish either because of theor accountability.
