Cost would be my guess. This costs less than US$20, whereas stream decks usually cost quite a bit more than that.

A Stream Deck is a bit overkill I think, but macro keypads are cheap enough that I'm also not sure why I'd opt for this product over one of those.

Thanks for the mention - I've always thought Stream Decks were kind of interesting, but overkill. It turns out a macro keyboard is what I really wanted.
