Irresponsible and stupid perhaps, but a lot of exaggeration here too.
I'd say the absolute worst case scenario is that the IFE crashes and must be restarted. Not a great result but not a plane crash and not a 10h flight without IFE either.

The other almost-catastrophic outcome is apparently that the IFE system would not just crash, but be bricked in a state where it couldn't be restarted. Not impossible, but not likely either.
People switch seats in planes without asking the staff. That's also irresponsible and dangerous, and the worst case scenario is a crash. This is about the same level of risk if you ask me.
