Come now, that's hardly fair - you are asking them to unilaterally open their doors And be open with their data, while the others would obviously not reciprocate.
Your standard for credibility ensures the speakers suicide, at which point there is no conversation to be had because the remaining players don't give a damn.
I suggest they acknowledge that business realities are driving them to do the same thing but that it would be better for everyone if they could find a way to cooperate.
Painting themselves as somehow superior while they engage in the same behavior doesn't seem likely to engender trust.

How do you suggest they go about handling this?
