But considering the internet is a nation-wide thing, would the state even have jurisdiction? If you never employ in a state and actively prevent access to the website from said state's residents, are you even doing business there? Sure, if FB employed Texans who work remote, they can't avoid it, but if they had no physical or even virtual presence? Because, in order to sue an out-of-state entity, you need to sue across state lines. That takes it out of state court jurisdiction and puts it in federal court. And in federal court, only federal laws apply. Is there any Supreme Court precedent for this situation?
