“this videographer is a slave”
Agreed, And a snowflake no doubt.
Any such actions need to be handled pre boarding or not at all. When passengers get to their seats there is a flip switches in their brains that says .... I made it, I’m on the plane, I’m settled in my seat, and so barring any accidents I have nothing to worry about until I land. So when approached about getting off the plane it’s completely unexpected, a shock, and the natural reaction would be to resist as their must be some mistake.
The airline has plenty of advance info to handle these issues prevoarding, and if something comes up post boarding then whoever is not in a seat should have to take the next flight.
