It's hard to get the whole picture out of this information but I think this is not aimed against bounty programs but it's about one particular case and probably some misuse that has happened. So I don't think this is something to panic and currently also can't see any connection to bounty campaigns or bad influence on them.
That was on my mind too, i'm sure there is a misconduct of the owner that's why they have to sue him. Most of the ICOs today are fraud and it is always a risk as an investor and this is the worst part, being scammed. If the owner had no problem at all of running their ICO then there's no pursuing going to happen once they are trustworthy from the start.
