First things first for you access those features on other systems you need to pay, and while I agree that Nintendo should have voice chat with friends(but even if it doesn't have it,why does that matter? I don't know about you but my pc is near my Wii U so if I wanted to play with friends online we could just use Skype or something else its not like you don't have any other options and Skype is not that difficult to download or make an account just saying),I think that vc with random people should be something the shouldn't bother with since a)VC with random people in MK8,Splatoon and SSB4 would be annoying and b)my brother plays GTA V all the time,he did it on the PS3 and PS4 and he rarely has to mute people and most of the time he is an full room so allot of people might not be use with it.
Also did you really just use SMM as an example has to why VC and online,since that game is not at all about multiplayer and about creating course and uploading them online and to play other peoples levels, yes even your friends levels, and a traditional Zelda should never be online since it's unnedded and not every game needs to have a multiplayer mode
