You might be right but I highly believe that it would increase in popularity once you have more local only devices in this space.

I have plenty smart devices with stupid apps, but I would pay premium for a quality product with a simple API and no third party servers anytime.

Personally I base many buying decisions around 'hackability'

Edit:// actually I think this is a coming market as Google only recently started to support smart devices without third party servers for their home app so before that local only ment no Google home most of the time.
