First, I should inform them about the legal and ethical issues of downloading pirated content. Maybe they didn't realize the implications. Next, suggest where they can legally obtain the software and tutorials. For Cubase 5, Steinberg has an online store, but newer versions are available. If they really need version 5, perhaps check if they can purchase a used copy through authorized resellers. For Antony Gordon's tutorials, direct them to his official website or platforms like Udemy where he might host his content.
