I was hoping this would explain why iMessage allows invisible messages and attachments. I really can't think of any reason why Apple would want to implement something like that, but they've been predictably used to infect devices.

If you are talking about malware, then there's no need for Apple to implement something like invisible messages. Malware essentially just exploits the parser, takes over execution, and never executes the code to display messages or puts them into the chat history.

This has nothing to do with the iMessage protocol itself. Invisible messages looks like a bug, as it depends on the current UI and rendering repercussions. May be if you file a bug on them they may respond.
