"Hey Joe, look at the news! If we use Messenger, we can't get wiretapped!" That's a limited ruse because at some point evidence has to be entered into the record at trial, and if the fact that the government could reach Messenger after all came out, this scheme wouldn't work again. Of course, often investigators can back-reconstruct evidence that they can present -- and if in some case they can't, well, maybe next time. Other times trial evidence might not even be a goal. So a limited ruse, but not that limited. Is it plausible? I think so. Is it likely? No idea.
