I dont know if it does or not but even if it did, that wouldnt make it free software. You cant compile your own alexa, or modify it to remove code you dont want, or submit improvements to it. Android is open source (excluding drivers), but google play isn't, and neither are the apps on it.
I gave my 60 year old mother my old PC running Debian with dwm as its WM.
She likes it.
> The idea that if these devices ran free software they would be more humane than the proprietary software they currently run is ridiculous.
Is it though? I am pretty sure that Amazon already gathers free data from its users, such a thing would not exist in a free as in freedom device.
