Known for their sleek, lightweight design, Apple products have a reputation as user-friendly. As late CEO Steve Jobs put it: Design "is not just what it looks like and feels like. Design is how it works."
But one former employee says Apple has lost its way.
Though Apple products are "more beautiful than before," they are harder to use, technology usability consultant Bruce Tognazzini told CNBC's "Squawk Alley" on Tuesday. The former Apple employee recently spoke out in business magazine Fast Company, saying that Apple is "destroying design" by focusing on thin, low-contrast fonts.
