Are landlines, like the ones found in commercial buildings, backdoored. Can we purchase development boards that the suppliers do not control after sale.
Whats difficult to get over is when non-tech companies, e.g., Bausch & Lomb, go along with the nonsense.^1 All this supposed corporate responsibility and yet they still partner with unethical "tech" companies.
1 Probably should not be surprised considering B&L is owned by Valeant Pharmaceuticals. (Who has sinced changed its name to try to escape its well-earned bad reputation.)
With Australian Telstra phones, if you called someone and they didn't pick up after a number of rings, a carrier tone would happen. If you whistled a handshake, the reciever would PICK UP and yes you literally turned it into a hot mic.
Since I no longer have a landline, I can't confirm it works now.
No they are not, because there's a clear boundary between your own device and someone else's infrastructure. And you could as well build your own landline system — which is exactly what people do in commercial buildings. You could also build some sort of scrambler device that goes between the phone and the line.
It's the same as asking "is internet backdoored". It might be wiretapped, but you can use encryption to avoid that risk.
