Don't be so quick to point out someone is wrong when you haven't thought through what you're talking about.
If you knew how a camera's exposure meter works, you'd know that it will determine exposure based on an average scene where there are roughly similar amount of darks and light. The camera's meter will be based on a given standard. Most cameras will get the exposure correct for the majority of such scenes. When shooting a scene or object where there is high subject reflectance such as snow, at the beach or an all white shirt and there is little if any proportion of dark tones, the camera's suggested meter reading will underexpose. In much the same way, shoot an all black object and the camera's suggested exposure will bias towards overexposure. I've used many different cameras over many decades to know what I'm talking about.
