I have a Roku, and I bought it for the exact reason that they don't (at least from what I can tell) have their own streaming service. I wanted a device where the makers have a direct stake in making the best experience for all streaming services possible, and there are no second class citizens.

I didn't want a device coming from a company participating in multi-sided markets. It just ends up with an internal conflict of interest and it's always not clear to the customer what side is the win.
