@evan I’ve always leaned toward having A's wishes respected as a first order priority.
I've worked to help platforms work through options for B to respond in a manner (it was a two tiered response model) where the one to A is clear, but one that filters out A from the response (either as script to remove it, or giving B the option for a public version).
These options were never implimented.
I know Traction software (for enterprise and “secure" focussed organizations) did this really well.
