It sounds like Nintendo is really trying to crack down on Switch modding, as a new update to Nintendo of America's User Account Agreement says that your console may become "permanently unusable in whole or in part" if you break certain new restrictions.
The new user account End User License Agreement (EULA) was sent out earlier this week, and as reported by Game File, it makes some significant changes to the second section, "license." Before we get into it, it's worth noting that Nintendo explains that the term "Nintendo Account Services" can refer to everything made available to you via your Nintendo Account, from games, to DLC, products, apps, services, and more – this phrase is about to come up a lot.
