Good point. The flatness of the design is irrelevant. The clarity of the communication is paramount. I agree that the OP may be favouring that particular design

Good point. The flatness of the design is irrelevant. The clarity of the communication is paramount. I agree that the OP may be favouring that particular design trend in his examples a little too specifically which is distracting from his (I think, good) message. Funny that he's championing "good content" but confuses his argument that way.
