Right. It's not a question of breaking the lock, because that can always be done. It's a question of "what's the policy," and "what is considerate of others." The answers on both of these are very clear.

using VOIP to talk on a plane isn't necessarily rude...... heck, I was on a flight last week from SFO to JFK. Two women on the opposite side of first class kept talking during the entire flight. They were so loud that I could hear every word they spoke. The only time they stopped was when one of them had to use the loo.
When the FA asked them "nicely" to keep it down... they responded by saying that they paid full fare first class tickets and shoudl be treated accordingly, not the riff-raffs who got into first class using upgrades. Where's the FAM in first class when you need one?
