Let this lady's reaction be a lesson to all of those who say "people don't care about privacy." She wired her home with Alexa devices, and yet when she found out how her privacy could practically be invaded through such devices, she seems like couldn't get rid of them fast enough.
People care deeply about their privacy. They just don't understand the true implications of even a device that's supposed to "listen to you" and the possibilities of what someone else could do to their internet-connected devices.
This is why governments must intervene with laws such as GDPR or even much stronger ones in the future to protect people's privacy, because the companies themselves have no incentive to "self-regulate" other than a negligible amount.
The only problem is some governments will not intervene unless enough people go through similar situations such as this lady. In the US even that may not help much because the vast majority of politicians care most about continuing to receive (however modest) donations (also called bribe money elsewhere) from the industry.
