Do I get to register preferences about what messages I will want to receive, or will some wanker with authority decide that for me? The last thing I want is for the person who decides which messages are important being of the same mindset as the nimrod who thought passengers at an airport need to be reminded every 5 minutes exactly what the list of banned items on airplanes are - again and again and again and again while you wait for your flight. (What's really dumb about that recorded TSA message is that it interrupts other PA messages that are NOT repetitive and thus should have higher priority. What's more important - the message that is identical to the one you heard 5 minutes ago and will hear again 5 minutes from now, or the message that's unique and you'll only hear once? You should never stifle the one-off message with the repeated one, and yet that's what airports do. (I just returned from a trip where I heard my name on the PA trying to tell me something and it got interrupted like this and I never found out what it was about until it was too late. It turns out I had gotten a standby slot on a flight, but missed the chance because the PA system was designed by morons who think recorded repeated messages take precedence.))
Anyway, I don't want the same sort of moron deciding what messages come to my phone (or worse yet, which ones are allowed to interrupt a phone call) without my say-so.
