Normally a document (chat) deletion schedule is completely fine and standard practice at most corporations. The problem is that it continued (without exception for those with data retention holds) once litigation had started. TBD whether using OTR exclusively (like having in-person real time meetings) for all chats would violate this. I guessing no, it's the choice to use OTR selectively by participants that causes problems.
