So how do you induce the incentives to create such open systems? Why does Roku exist to connect any TV to nearly any service, but not the same thing for IoT? Is it the insistence on making money through services rather than the lower-margin hardware? (Noting that Roku also makes money through channel placement and probably affiliate fees.) I'm afraid that the only way it's going to happen is if the government wades in. But first enough people have to give a shit about these systems, and that'll require them actually being useful to a majority of consumers.
