Oh I didn't mean your post in particular containing exaggerations, more that there is generally a lot of talk here insinuating plane crashes or other catastrophic side effects coming from port scans.

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.
