Sadly, you're probably right on target. Sigh.
What's really amusing (or is "sad" the correct term?) is that the announcements provide inaccurate information. Take for instance the A330 doors that have slides that can be used as rafts. The new mandated announcement incorrectly states that the forward and rear slides can be used as rafts--there is no mention of the 2 L and R doors which also have slide rafts. I guess we're either not supposed to count them, or only the people who are seated behind them are supposed to use them in a water evacuation. Then there's the boarding announcement that doesn't mention the flight number, destination, or even has the words "welcome aboard" contained within.
Morons, I tell you. Morons.
