My favorite one continues to see the 1000+ dns requests that my Philips Hue lights send after disabling diagnostics on them. It was the same beforehand :)
Hah, what a strange dystopia we live in where it's impossible to stop your LIGHTBULBS from tracking you via the internet!! I'm a total curmudgeon about smart home stuff, I don't want any of it beyond a TV in my house if I can help it. It freaks me out seeing people with no technical knowledge outfit their entire home with Nest/Ring/Google Home/Echo/Phillips Hue and even smart refrigerators, while they know virtually nothing about how much privacy they've just relinquished to these companies and they don't have the technical skills to even attempt to mitigate it. I feel like a paranoid doctor who's starting to notice the damage done by cigarettes while the general public is still blissfully puffing away...
You are not alone. It's pretty heartbreaking to see how so many promising products are really surveillance nightmares. I've noped right out of using some nice-but-not-necessary features on some things, because their app wants location access, contact lists, or other things they have no business accessing. WTF?!
