My apartment complex came to install keypads and centrally managed smart thermostats and I would not let them.

Thankfully my lease was old enough that I was able to argue against it. I don’t want a 3rd party company tracking my habits, and I don’t want some manager boiling my pets alive while I’m gone because they decided they think our AC is set too low.

You got lucky. If you've got an apartment in, say, a healthcare facility, they'll install those thermostats and whatnot. Usually the neighbours are clueless about technology so complaining doesn't get very far at all.

It's even worse if some staff wrote paranoid in your file, 'cause they'll argue it's good for "exposure".
