I see no justification for this much benefitv of the doubt. Jason Scott is no rando. Vcf claim to be in the business of preserving such material, or at least recognizing that it should be. The material was topical, and all parties know each other.
Very clearly and with no ambiguity at all, it was vcf who totally failed at their task.
I don't define "their task" as simply "posess and operate an excellent document storage facility", but merely be minimally professional and responsible enough to avoid accepting material they are unable or unwilling to deal with, and if you do accept it and then change your mind, find someone else or go back to the doner, and suck it up until you can undo your mistake.
This is not a "miscommunication". The people involved and the context does not allow anyone to claim anything like that.
A random person didn't dump a truckload of random material on the front lawn of another random person unsolicited.
A famous vintage computer organization accepted a set of vintage computer documents from a famous archivist.
vcf accepted responsibility for the material, and then, I don't even know the right word, they didn't merely fail, that implies trying, what is failure to discharge a responsibility when you don't even try in the first place? What is the excuse for not even so much as iquiring if Jason could possibly just take it back? How much does an email cost?
