I know what they mean about ease of use, too. In the early 2000's I had a Garmin eTrex GPS receiver, the little translucent green one. Did a lot of hiking and geocaching with it, hooked it to my laptop for wardriving, etc. And everything I ever asked it to do was so easy -- there was no touchscreen and the click-stick only had five "buttons", but the UI was just profoundly intuitive.
I said at the time that if Garmin ever made a cellphone (this was pre-smartphone and every phone reinvented its own craptastic UI), I'd buy one in a heartbeat. Of course they did release some Garmin-branded phones later, well into the Android era, and the UI is generic Android. So much for that, and more's the pity.
But I believe their marine instruments retain some of that old-fashioned intuition, so anyone could just walk up and figure out the interface. And that plays a role in the story, so it's absolutely relevant to mention.
The heroes of the story are the two men.
It would be like if someone were about to sucker punch a woman and you happened to be standing in the way. You're not a hero, you just happened to be present.
It's also a type of scare mongering. "You might fall overboard while peeing, and our product could save your life, just look at this phenomenally unlikely scenario!" The much smarter solution is to use a wireless lanyard or just pee inside the boat, as commented elsewhere here.
