A wire will also record anything around you that is not necessarily directly related to your actions... so in some potentially-important ways they are significantly different. Though the argument for "I was not aware, being in X group does not mean I follow all messages" is also entirely reasonable, e.g. I'm in several hundred slack channels at work but I only closely follow like a dozen. But yeah, I think "let's go off-record" is almost equivalent to "let's destroy evidence" when you are informed you're being monitored for legal purposes. Innocent until proven guilty is deeply critical, but when you're informed those suspicious actions are doubly suspicious and there must be some kind of room for suspicion or criminals will always be able to avoid conviction.
