I'm another one who is frankly shocked at the amount of people who have no idea what their tech is actually doing.
I have been banging on about this for years, get laughed at because I tape over my laptop camera, and switch all the microphones off on all devices, including phones and tablets.
They stopped laughing when all this shit started cropping up, especially when it turned out even Zuckerberg tapes his camera.
I also run VPNs, ad blockers, disable all trackers/cookies etc and my social media accounts are as anonymous as I can make them.
Yeah I am that paranoid!
I would never, ever have a fucking listening device in my home.
You are voluntarily opening yourself up to constant tracking, revealing anything and everything to everyone.
I think it's a little more insidious than simply using humans as a currency to sell to other giant companies, although I think that's bad enough!
Having seen what hackers can do, with a cheap laptop, to anything from smart systems, to your pet cam, to Alexa and even to driverless cars (that was scarily eye opening btw!) I am not keen to be open to that sort of abuse.
I also thinnk that Govern,ents the world over are rubbing their hands with glee as the next generation become so desenitized to being online, tracked, followed and putting hackable devices in every corner of their homes that should a Government ever want to abuse this (and they almost certainly do already!) it will be like shooting fish in a barrell.
