It is understandable, but if that is happening then they need to issue a final firmware to ensure software doesn't start crashing from the network stack hanging, like it already does in Art Academy Atelier when they killed the Miiverse, forcing users to disable networking in the settings.
Nintendo consoles have always been more robust for me than other consoles, but the abandonment of the WiiU bug squashing with firmware updates would have never happened if Iwata was still alive IMO. Games like Batman Origins being poorly tested causing the console to lockup in the first 10min intro and then sporadically throughout the game really isn't on.
Hopefully in putting the console out to pasture they will do one last firmware to squash loads of bugs so it will continue to age as a great last Iwata/Miyamoto console.
