To be honest, yes, it used to make me angry. But then I realised that startup world (and blockchain in particular) is like that and there is nothing that can be done, because those are the rules of the game. I often stumble upon a project that fails but also there are some good ones. Instead of wasting energy on being angry I simply move to the next one and try not to make mistake. HEAT was expensive lesson, but worth it. Many people in this community are still naive and hoping for the HEAT bull run, others are still angry, but IMO best way to deal with it is simply move to the next project. That being said, if you would be doing any lawsuit you have my sword and probably some other people would join you too, but I guess you would need personal data and that would require loss of anonimity, so that should happen as further into the preparations as possible, because probably people will not be eager to share that data before they are 100% sure that lawsuit is happening.
