You can not possibly examine the evidence and claim 100% that there is no interest in spying on anyone.

Doubt that this particular case has that as the core issue? Sure. But be utterly convinced that literally no one, in any intelligence agency, against any target that might be near some sort of microphone-enabled device, has ever had the thought cross their mind that these things might be useful? No intelligence agency has ever looked at one of these companies hoovering up all the data they can get and installing all this stuff everywhere they can and stroked their chin for a moment?

You're basically claiming the NSA, CIA, Mossad, KGB, MI5, and all other such things have never existed, do not exist, and will not exist. The evidence for this is pretty poor.

I'm not asking you to wake up tomorrow and worry about whether your toaster is secretly sending all your thoughts to the alien overlords, but come on. Live in the world a bit. We're 7-ish billion people here on Planet Earth and they are not anywhere near all to a person nice, wholesome people who wish you all the best and would never even dream of exploiting you even a tiny little bit while they joyously enable you on your life journey of exploration and wonder. You're begging for exploitation.
