I think having all of this stuff behind a firewall and not exposed to the internet makes a pretty big difference. If an attacker gets onto my LAN, it's game over.
Mass produced consumer gear that is also perfectly secure probably doesn't exist. I assume everything I use has bugs and none of it will stand up to a dedicated attacker.
As for blackmail, my cameras all point outward. I suppose they could threaten to report me to the HOA when my grass gets too long...
I'm almost certain it does have the same issue. I don't believe there's any networking gear out there that is believed to be bug and exploit free now and expected to stay that way in the future.
I believe a dedicated hacker could use the microphone and camera in my phone and laptop to spy on me. They could look at the street in front of my house. They could see my entire browser history, everything I've printed, every call I've made, everything I've said over email or text message.
