A decade ago during a project, I was griping about the trouble friends of mine had been having with their landlord, who was controlling the thermostat remotely to save money (rent was inclusive of bills). This was a shit thing to do when you don't know a family's schedules or even the local weather… But when I was venting about this, the other devs got defensive and angry. Turns out they were both landlords who did exactly the same thing to their tenants
