That's such a poor argument. What is the alternative here? Just let anyone fly with a dozen devices with the names BOMB and CRASH hoping that an actual bomb doesn't go off? Systems and processes exist for a reason.
Your example of 150ml liquids has no connection to this security measure nor incident either. That's just a straw man.

That sounds terrible. Please get me the manager.
I think there’s a safety issue that isn’t necessarily reliant on ‘bomb’ being an explosive device: it’s the impact on other passengers.
Planes traditionally have avoided certain kinds of movies and such to avoid creating panic in the cabin. Here every passenger is looking at their phone, and if one guy makes the obvious “there’s a bomb on the plane” joke, the captain/crew could be in a situation.
Crowd management is essential to crew safety and crowd safety.
