Need is the operative word, there isn't a need, sure there are technical people that want to poke around or the "because its mine/I can" crowd but for the vast majority of console players they don't even know what SSH is.
I started playing games back when you had to mess with and resolve IRQ and DMA conflicts in DOS so I love having a console I can use as an appliance. You don't need SSH on every internet connected device you own.
Game consoles have a very strong case for being closed because cheating ruins their primary function. And players absolutely will cheat even if it means spending thousands.
Other devices do need some level of local access because bad software is often the limiting factor of usefulness.
