If you were in a one-party consent state (ideally without notification required), you could just transmit audio logs of "all incoming phone calls, for customer service and quality control purposes" to a third party, and the third party could choose which to publish. The third party would be under no obligation to keep it secret, and the caller would not know which third party to contact to get an injunction to prevent publication.

I imagine if someone tried that, the NSA/FBI would merely say, "hey, head down to our office, we want to talk to you about something."

Continuing that I wonder if you could have webcams in nearly every area of the building and make it all publicly accessible.
