Some people claim that they want personalized ads (at least on HN and similar communities)
I've never met anyone in real life who wasn't creeped out by a targeted ad. Everyone nowadays has a story about how they were having a conversation with someone about something, and then one of their devices served them an advertisement for the thing they were talking about.
Everyone finds that creepy as hell, but it's hard to attribute it to any particular device/company, and even if you find out that it's your Alexa that's spying on you, it's hard to throw it out. Not only is it a waste of money, it's a loss of a convenience, and there's some social pressure involved. Like do you really want to be seen as that one paranoid weirdo who doesn't trust technology that everyone else is using?
Alexa... well you paid for this device to spy on you so that definitely should not surprise anyone.
I think it's bizarre that people are not only OK with having their house bugged with a device that listens to their every conversation - but they're happy to pay for the privilege.
Do you know that when you have an argument with your partner, Alexa is listening to the whole thing? Sensitive business meetings... etc... very strange!
