Give it a year and I'll bet we'll have stable CFW for the Switch as well as an easy access point, so there will be no need to buy an expensive tool.
I understand Nintendo banning online access for consoles that pirate, but it also just encourages them to pirate more because they can no longer use the eShop or any online-related services. If they pirated a little bit before, they're DEFINITELY going to pirate everything now that they're banned and can't do anything.
But I can see why Nintendo would ban people who are tinkering around with the system with mods...this is how people start cheating in games like Mario Kart and Splatoon and ruin the experience for everyone else. Seems like a pretty decent compromise...if you want online and eShop you have to stay vanilla.
