I'm not sure how much I'd trust Amazon on that one...

 Along with receiving  his own audio history captured by a home  microphone, the user also  gained access to 1,,700 audio files from a  person he did not know.
 Amazon  sent the man a link that contained a stranger's recordings,  allowing  him to listen to another man speaking inside his home with a  female  companion,

 To me ok, it's bad that they sent the wrong recordings, but I'd be  more concerned that they are keeping recordings of stuff you say around  the house.  It's like we have decided to just invite surveillance into  our own homes, and who knows who really has access to them.  No thank  you.  
Now, would I trust buying a Nest over a Hikvision?  Sure, absolutely. 
Sorry if this is a little off topic, but I think these considerations are important when looking at what devices you get.
