In general and long-term I agree with what you are saying. I assume this was a new/unknown situation. (On the other hand, the article links to other similar stories, so maybe I am cutting them too much slack). If "electronic device names" are of concern, there should be an established protocol to deal with them. Especially if this keeps happening.

IDK, this was pure technical incompetence by rubes that can barely operate a smartphone. The delay relies entirely on these supposed "adults in the room" overreacting.

I think this is just the way the decision tree works in safety-sensitive areas where many human lives are at stake. The catch-all in the decision tree, if there is no exact solution, is always the "get to safety at all costs" option. There will be some window of trying to resolve an issue (here: telling everyone to shut down devices) and when that does not resolve the issue, the catch-all kicks in. That's just the pattern and in an environment like an airplane, where margin for error is slim to non-existant, there is no deviation from that pattern.
