Those in-home alarms that can talk to you... if they can talk TO you, they can also listen.
Also, anything can be hacked. IMHO
Pretty soon, there won't be a choice... to not be spied on.
I think I would more respect for the one that may hack into my Smartphone. I expect a hacker to be an unethical putz. It is the companies (Mattel and Facebook, for example) that pretend to be wonderful, while tracking a person's every move.
Unless I want to live in a box....
