We all make the calculation whether it is worth it and for me it is worth it. I'm not a head of state or someone with great secrets to keep. Alexa just hears me talk a lot about Elden Ring or whether we need to buy milk. I'm just a normal guy talking to his girlfriend and for me it is worth it. I completely respect the opposite view though. For me the pros outweigh the cons. I have good reason to believe that they are being truthful when they say it only hears me talk when I give the wake word.

I think you would have a lot more cases than this if it heard you at all times. It seems the police only have access to the times the word Alexa was used.
