Perhaps I didn't explain it well. Those employers kept me ! and I didn't have to repeat it to other potential employers "shortly" later.
It just ended the conversation there. The crucial part being I'm not against publishing as a part of my job, but no way you're making it a personal requirement / on my behalf.
The outcome being "let's stay good friends", not "you're fired"/"don't get the job", I did get it. As such, not ending the conversation in 2 mins but letting them reviewing their argument is crucial : the constraints are yours, and you don't have anything to blame me for ..
