Umm... Cel-shaidng was introduced long before Wind Waker and a lot of the cel-shaded games coming out were announced around the same time as Wind Waker, too soon for it to have been taken form WW.

Also, considering the bad reaction to Wind Waker's cel-shading, I seriously doubt that other companies would decide to make their games cel-shaded games because of it.
