Actually, I would hope that Mr. Fischer could be appeased by an apology. Not from BA but from the CC that caused the problem - by not applying BA policy and engaging one's mouth before one's brain.
I also hope that BA has a second thought about this. If they are going to take responsibility for the UM, they simply cannot dump them in a seat 'near the galley' and hope for the best. Why not confirm a stand-by staff member to sit next to little precious?
