Using a three-blade IEC connector and not connecting the safety-earth pin inside is the low frequency equivalent of lifting the ground at the AC plug with a cheater.
However, it does connect the safety-earth wire inside the power cord to the house AC safety-earth wiring. This allows the power cord safety-earth wire to resonate and receive noise, and convey the noise to the house AC safety-earth wiring network. It also allows this wire to convey noise already on the house AC safety-earth wiring network to the hot and neutral wires in the power cord.
This is a compromise. A better approach would be to use a two-wire power cord.
