Interesting but not really alarming.
This article is saying that if someone breaks into my house, they can hack the Echo and use it to record my conversations. If someone is going to break into my house to monitor me, I’d be more concerned that they’d hack my router.
Agreed that this isn’t very concerning. If somebody’s willing to break into my house to get information on me, Alexa is the least of my worries.
That said, I don’t own an Echo because the prospect of Amazon (or any company) listening in on me is creepy.
