> everyone is doing it
Not in my house. What is even the point of connecting a coffee machine or a washing machine to the internet? I think my washing machine advertised that I could download new washing cycle programs in the app. Who on earth cares?
I could see its use - you could remotely activate them. Or activate them on a timer that isn't constrained by the functions of the coffee machine.
None of these are worth the spying that these companies do though.
