I’m sure someone will provide the twitter links because I can’t, but do far there have been two messages. One from Bastion, one from Winston.
Of course, Bastion is…Bastion, but Winston is asking for a password to decrypt a message.
Now this could just be me, but we know Null Sector has used Bastions in the past, and if I’m right and these coded messages are from Null Sector…then it’s possible Bastion could be the only Omnic capable of deciding that message.
ESPECIALLY if Null Sector was attempting to use an outdated code to make things more confusing for anyone intercepting their broadcasts
