Many people that don't keep up with technology news are, at best, vaguely aware that Apple is fighting a court order to create a tool for the government to unlock one of the San Bernadino terrorist's iPhone.
What the FBI is asking for could jeopardize the security of all iPhones. Besides the obvious possible slippery slope leading to governmental abuse of this technology they're asking Apple to create, there is a more personal reason for many ExJW's to be concerned about.
Anytime you create a weakness in information security, there is always the possibility of that weakness being exploited. Sometimes, those weaknesses are difficult to exploit, sometimes they are easy. Sometimes, though the weakness was difficult to exploit, once it is exploited, tools can be created that make the weakness easier to exploit.
Think about an undercover ExJW. Perhaps he is married. Perhaps the only place he can do his research and vent about his situation is on his phone. Perhaps his wife is suspicious, but she doesn't know how to get into his phone, so she has no proof.
Well, if the FBI requires Apple to create an OS vulnerability for their purposes (which is exactly what they are asking) that opens the door to the possibility that due to this poorly conceived quest of the FBI's, the undercover ExJW's uberdub wife could someday have a tool that unlocks the phone.
Now think about it from the point of view if the undercover ExJW was underage, and it was his parents unlocking his phone.
This is serious business, folks. The decision in this case will have far reaching consequences for National Security, personal privacy, and protection of whistle blowers.
Tell the White House why strong encryption is important to you.
