ALSO I just noticed this but can someone (ideally from JetBrains) explain what this line means: "Requires login and periodic connection to JetBrains servers to verify the project" (specifically the last 3 words of that sentence). Quite frankly this line is extremely alarming, are you saying that you're scanning my project to make sure it's not a "professional" project? I'm going to assume this line means that they are checking the IDE and not your source but I won't be using this product until I get an explanation for this. You can find this at the very bottom in the licensing and pricing section.
