If they refuse to write it down even in an encrypted email, or some form of secure communication, then I would say even if they have good reasons to avoid making things public, it would count against the ‘genuineness’. Since it would be very unlikely for their to be any bonafide fears of man in the middle attacks and so on.
The only legitimate reasons would be mistrust between the parties, e.g. fear of accidental or intentional redistribution to third parties, insecure records management, etc,..
I’m not sure if you considered the relative security vs exposure tradeoff but, other than mistrust of the counterparty, there would have to be some stupendously, world shatteringly, important reason, for me to not get suspicious if they flat out refuse every secure means.
