I've been generally dissatisfied with the smart watch options in general, even more so than cell phones and the Sophie's choices for cell phones is pretty bad!

I've been generally dissatisfied with the smart watch options in general, even more so than cell phones and the Sophie's choices for cell phones is pretty bad! What factors prevent open source hardware from being viable? Like if the basic parts of the pebble (e-paper screens, small efficient processors, flat batteries, etc) were open hardware so that any number of manufacturers could just churn out the parts; and if there was a FOSS option for an OS to run that hardware; what prevents a vibrant community from forming around those options? We could have artisans putting together various nice watch options, and lots of little apps to run on them. Why don't we have that?
