I don't understand the shadenfreude either, but for the opposite reason. I think most people who have Nest products also are in the Google ecosystem, and are probably happy that they now have a Google Home for free.

Considering half of the other Nest products contain microphones already, I don't think anyone who truly is worried about this stuff would've gotten a Nest ecosystem to start with.

I agree, it's important to have all the facts so you can make informed decision, but this specific case has been way overblown, mostly by people who don't use Nest nor ever will. Almost anyone who's outraged probably would've never bought the product anyway.
