The alleged crime sounded childish. Appeal to rule of law, enforced by the court system is necessary for a fair business enviornment.

Sending the notification letters is probably petty though.

These letters are simple "If you have evidence related to this lawsuit, you must preserve it" letters. And entirely routine in this kind of action. There are more of them than in most cases, because this is such a big case. But the gist is entirely routine.
