There’s a limit to that. By that token, every logo in existence could be a white square with black text on it. Clearly they are not, because people understand the need for some differentiation. Even in this case, the logos benefit from having colour. And they’re not even consistent. Three of them are squares, two of them are different shapes, and despite the simplicity even something as trivial as the font size and spacing isn’t uniform.
