If you want to lecture these people about anything, it should be over their failure to carry enough water before entering the desert.
It would be an even bigger mistake if they did not bring enough air. Seriously-- you can't even breathe without that stuff and junk.
Or, develop a good relationship with your children
This part you got right.
instead of once again relying on technology to babysit for you.
Being aware of signs of trouble is a necessary part of what a good parent does. This particular technology is not a babysitting technology, such as TV (or invisible fencing?), that implies parental neglect or shirking of responsibility. This is probably worse, in that it involves clandestine monitoring, implying that you are suspicious of people you love. Neither provides a solid foundation for a relationship, but there is a distinction.
Talk to your kids about behaving responsibly, and openly talk with them about their concerns, and yours.
Sounds like a cheesy anti-smoking commercial, but I completely agree with the statement. Resorting to spying, snooping, or any type of deception will just damage your relationship because it means you mistrust your children. You should trust your children, but that does not mean you let them do anything they want without oversight or supervision. You trust them to make good decisions, but you keep an eye on them to help them when they don't.
(And no, this comment isn't Insightful or anything else; actually I probably HBT).
Or, how about the reward is that you acted responsibly, doing what you thought was the right thing. Can't that be enough?
