Maybe he could have done all those, maybe he did have all those things, but he had a phone that could effect a rescue and get him home faster so he wouldn't have to spend a cold night out there or walk/snowshoe 20mi to the next point of civilization. And you're grumbling about that why, exactly?
If you were in that situation and got to go home to a warm, dry bed or spend a night freezing your whatever off, wouldn't you choose trying the phone and getting a ride from the people paid by your tax dollars and your purchase dollars to do exactly that (and some volunteers who do it because that's how rural communities function, too)?
I spent many years as a firefighter, paramedic, high angle rescue tech on departments that actually ran these calls in urban and remote, rural mountainous areas in the Rockies in CO (and live in Telluride now), so believe me, people who aren't prepared exist and I have no real love for those who do it wantonly or with extreme ignorance or arrogance, but really, if you have the option to use a communication tool to prevent needing to really rough it, you should, and, honestly, you've made rescuers' job easier because if you can walk out on your own power and we just gotta take you to your home/car/whatever it's a LOT easier for everyone than once you're starved, managed to step into a wet stream though some ice, or whatever because you were too damn proud to use the tech you had in your pocket.
That doesn't mean people shouldn't be prepared or use satcom as a false sense of security or excuse for being prepared, but if you're fully prepared to spend the night but can easily avoid it with some smart use of tech and that means you aren't getting rescued in the middle of the night when you've run out of emergency fire and shelter or whatever, geez, that is GREAT.
