Its impossible to do with anything that gets updates. You never know what the next update will bring. Obviously things that connect to the internet and do not get updates are hopelessly insecure. its also pointless for anything controlled by an app through a server (anything from cars to fridges these days) as you cannot control what the server does.
Governments will also find excuses not to do this as its expensive and inflationary. They will play down the risk, point out the Americans can do it too, etc.
I think that the sorry thing about the article is that, even though I've read through an article of yours, I have learned nothing about what kind of person you are. I think that there's more to blogging than just showing the work. It's also a stage for you. The displays of character in the article ("I had a feeling", "I sat with that for a minute") written in first person are not actually yours, and are instead, in a way, a performance of the LLM that you used. So in my opinion (and you're free to disagree) you've robbed yourself of the attention you deserved.
However, I assume that the contents of the investigation were true, and if so, they are quite damning (in fact, my SO has just surprised me with a cheap Chinese projector. Nice timing!). It was also great that you've shared the prompts and results at each stage.

>My $35 projector wasn't just spying on me. It was selling my network. Anyone who paid Kookeey for proxy access could route their traffic through my IP
$35 for a projector should cause you to raise at least one eyebrow.
Also, as always with “IoT” type devices, they’re best kept in an isolated VLAN with no internet access.
