Sounds as if you might not have dealt with corporate litigation. There's no need for courts to issue subpoenas. Lawyers can issue them too, and for practically anything. If you don't respond they can issue a motion to compel in court, which if granted means you are legally required to respond with the requested documents. The real problem is that all of this starts to get very expensive if you want to fight it. Meanwhile, all those lawyers need is to grab your text messages, emails, and slack messages. There's no need to look at code. If you have been up to something it's likely to come out pretty quickly. p.s., Hiding your tracks after a subpoena is issued is a good way to end up in jail, at least in the US.
