I wonder if there needs to be an "NDA for feedback"... or at least a "non-disparagement agreement".

Something along the lines of "here's the contract, we give you feedback, you don't make it public [is some sharing ok? e.g. if they want to ask their life coach or similar], if you make it public the penalty is $10000 [no need to be crazy punitive], and if you make it public you agree we can release our notes about you in response."

(Looking forward to the NALs responding why this is terrible.)
