They charge you for the product on subscription and then take a cut of the total mined currency (I beleive 15%). If that isn't all upside not sure what is.
I'd suggest you follow the site guidelines as well and comment to add value.
"Norton gets the coin" absolutely suggests that this is nefarious mining where Norton gets 100% of the value. That's demonstrably false, and just because Norton is a horrible company with horrible products doesn't mean we need to pretend it's something it isn't.
