I've seen a lot of comments online talk about how in the US people are very litigation-happy and the law enables it. Does your situation exist because you're located in the US or is your situation something that would happen anywhere in the world?
While the US system may help nuisance lawsuits, it also allows the justified Davids to take on the Goliaths. Not sure how to stop the former while not stopping the latter.
I can't really say, because I lack sufficient knowledge of legal systems outside the US. I really only know what I know about our current system because of this lawsuit. I'd prefer not to know any of it! I just want to build great products.
