It's your prerogative who you sue, but again, i'm just describing how the law works in relation to copyright suits. That situation matters because there's no international law that says whoever you sue has to fly to your country and show up to your lawsuit, it's that the UK only has jurisdiction over the UK (and incidentally some jurisdiction over commonwealth nations via AJA 1920). imagine it weren't 'some guy' but a US-only startup selling only to U.S. based firms and they were valued tomorrow at $100B, regardless of their size you wouldn't have a way of seizing their property since the UK can't seize property in another country (I guess not without that country's permission). The only way they would be punished is if they're sanctioned and thus can never do business within the UK, or they get extradited some-how some-way. Microsoft indeed will show up because they want to keep selling Windows and Office 365 there, but otherwise, as I've said, copyright lawsuits across nation state lines and not within a single country basically don't happen.
