I forgot about that, but regardless it seems wrong to post a photo of a FA regardless of whether she was the one who booted them or whether it's just some random photo of a FA in an airport.
I wonder whether the seat switch moved the autistic kid into an exit row or something similar happened.
Also, I suspect that this gets back to the simple fact that if people want to sit together, they should reserve seats together (and not buy BE fares, if this is what happened).
