The megathread was already five hundred pages deep. The title said it all:
Using patched NSP files on a Nintendo Switch typically requires a custom firmware (CFW) like Atmosphere. It also violates YouTube’s Terms of Service and Nintendo’s EULA. Your Nintendo account and console risk being banned from online services if detected.
: Some older versions (e.g., v1.0.0) accidentally allowed ad-skipping by returning to the Home menu, a feature patched in the official v2.0.0 update. Key Limitations and Risks
On custom firmware like Atmosphere, a patched YouTube NSP can allow the Tesla Overlay to function while the app is open, enabling hardware monitoring or cheat menus while watching tutorials.
When the user launches the "YouTube" app, instead of loading the standard video interface, the console executes the embedded exploit chain, crashing the browser process and gaining code execution.

The primary and most significant risk is a permanent ban from Nintendo's online services. This is not a minor inconvenience; a ban means you lose access to the eShop, online multiplayer for all games, and any cloud save features. Installing any NSP file that didn't come directly from Nintendo is a highly detectable action. As noted by the community, "À partir du moment où tu installes un nsp tu as un risque quelque soit le cfw..." ("From the moment you install an NSP, you have a risk, regardless of the CFW...").
