Someone has finally identified the market opportunity to sell a home assistant that protects your privacy. Devices like Amazon Echo and Google Home are sending everything that happens in your home to the Amazon or Google mothership: what music you listen to, what you are talking about, what programs you watch, what you buy....everything. Apple's HomePod also sends everything to Apple for processing, but Apple has a much stronger commitment to protecting customer privacy than Amazon and Google (the latter two don't really promise any privacy protection).
The Mycroft Mark II "Open Voice Assistant" is similar to the other devices in function, but the software uses open source code and more importantly, personal information is not uploaded to a corporate database.
I think we will see more "open" devices like this as people slowly begin to understand the extent of the data collection going on with the corporate devices.
