You may be right: money talks.
But wait! A further twist! The airline could let people use their cell phones on the flight (thus generating revenue)...and then also create a "quiet zone" for those who don't want to listen to the ring tones and conversations - but charge people £5 or £10 to sit there, just as some of the no-frills carriers do with extra legroom seats. I can see it now (and it's not a pretty sight...)
