Sure, I'm happy to admit you may be right but I am yet to see a single - even theoretical - case in which the encryption I am using may be decrypted by a third 'MitM' party. The SIS/GCSB/NSA/FBI and any other acronym are welcome to my encrypted packets for all the good it will do them.
This makes the assumption that they haven't stored them until they can be decrypted and time travel back in time in electronic media is not possible.
When I consider the rate at which computer speed has increased over the past 45 years, I wonder what encryption you're using.
