The problem (aside from this being illegal and destructive) is that the type of person that‘s likely to go out and purchase a poorly-secured „gee whiz“ IOT device or router without considering security — is the same type of person that‘s not going to understand why that device just stopped working for no coherent reason. As a result, they‘re likely to rush out and buy another, poorly-secured device, bringing the incompetence full circle with a zero net gain.
