I agree, at this point if you do anything tech related you are infringing somebody's patent on something. Whether you get sued or not depends on how much money you have. As for the legal extortion using lawsuits. That's an old game in the US, there are people who make an active living out of suing somebody for something and offering to settle. Get a copyright infringement letter from somebody? I guarantee you that the settlement offer will be much less than defending yourself in court, even if they are mistaken in their accusation. It's an industry that people have been abusing for years, if not decades. The courts themselves have to do something to stop this but I see no signs they are interested in reducing the need for more resources to be spent on things the courts need to address these cases.
