Its a matter close to my heart days, still having delusions of being a mobile app developer, and hoping to have Apps downloaded from US servers hence subject to US legal system. The root problem seems to be the US culture of being entitled to your 'day in court'. If you take civil action in the US and lose, you normally only have your own legal costs whereas in the UK the 'loser' normally pays both sides' costs.
The US sytem has its merits, for example I were wronged then I could sue a huge US corporate organisation, without having to worry about their legal fees if I lost. But if I were to be sued by a troll for one of my apps , even if the suit was completely frivolous and I were 100% innocent, and even if it went to court in the US and the jury agreed that I was innocent, I'd still be bankrupted by the cost of proving my innocence.
I hope they manage to fix the system, it just doesn't seem right.
