I would suggest Roku make a digital assistant as well but it would probably come in 4 different models ranging from wholly unusable to outrageously expensive, have a purple bow tie, and need to be replaced annually with the latest model.
After all, it even has a VLC app...
It's why I canceled Amazon Prime (Funny, after being a customer for over a decade, with Prime since it was offered, cancelling was a single click, with zero follow-up or attempt at retention. Not even a "Oh, hey, why did you decide to cancel after so many years?")
Not sure why Spotify isn't using it.
It's basically a hard coded list of events that get triggered if someone says a particular phrase.
Spotify's use case isn't supported.
