It is probably unfair to go after Amazon and their Alexa, but this time it was them.
Amazon confirms that Alexa, their Virtual Assistant, was triggered by the sounds in the home to start listening, parsed the following information to mean it should send a message to a contact and then started recording.
The contact then received the recording from the private home.
The Dark Pattern here is that it is very easy for the users to activate the virtual assistant, and have it perform a series of actions, by accident.
But of course the question could also be, who on Earth want to place internet connected recording devices that are always on, in every room of their home?
