Why no PS PLUS type service on Wii U?

Its perfect for a free service. It works very good and I rarly get any lag......and that''s in Smash online 4 players where some are in Na/ eu.

i've no doubt it works well. my point is in relation to it having so few online games. 

So how will having a premium service that gives away games lead to publishers to make more online games? They would still need to add those games and since they're giving it away for free it wouldn't lead to more online games being made.
