Whether you are a journalist or an abused individual hiding from the ex spouse/parents/whomever that abused you, if your life and/or the lives of other people are on the line, this detail (and perhaps others, as I am not super technically literate) is a serious deal breaker.
It has nothing whatsoever to do with some kind of vague, hand-wavy preference, like preferring red phones over blue ones because you like the color red. It has to do with "If I use this, will I or others end up dead, maimed, in jail for a lot of years or otherwise basically have one's life utterly ruined?" Like that movie scene where they blow up everything "because you made a phone call" (Enemy of the State, IIRC).
