I don't know that they have said "no" to it. I just don't think they've actively pursued it. Hulu and YouTube are both available on Switch. I have a Hulu account, but I almost never use it on Switch since there is a Hulu button right on my TV remote. Accessing the app through an additional external is redundant and unnecessary. Same goes for Netflix, Amazon Prime, etc. With the proliferation of Smart TV's, there's less need for consoles to be used for these features. You shouldn't need your video game console to be running all the time if your aren't playing games on it.
That's a fair point, but again, the Switch wouldn't lose anything for having more features, even if they are redundant. In that sense I would have to agree with @The_Yoda, since preventing a possible doorway to piracy may be worth sacrificing some features. But then again, nowadays a console is going to get hacked no matter what, so I'm not sure if the rewards would compensate the losses.
You know it deserves the GOTY.
