No, the poster is correct. The metal grating that you look through is designed to block the microwaves. The wavelength compared to the holes is the important part. A microwave oven operates at about 2.4 GHz, which translates to a wavelength of around 12 centimeters. Those little holes are usually only a couple of millimeters wide.
