This is the type of thing that law firms will send without consulting their client first as soon as they were made aware as a default response, without considering any context to verify proper action. Which in most cases would be fine, but in this particular genre, because of shitty companies like Nintendo, can cause direct reputational harm.

It is Wizards of the Coast though, historically they’re not much better, so this would be 100% believable coming from them on purpose.
