My favourite example of "Modern" style is the toggle switch, shown even in that image. I laugh a lot of the times I see one, it's the 'replacement' for the checkbox, but it's so awful at actually telegraphing it's current state in a consistent way- (the entire purpose of the control!) that it has to have a label indicating whether it's on or off. I find it so absurd that people genuinely put this stuff into their programs and have no problem with it, because apparently we are just supposed to accept this type of poorly designed component because it's more "Modern".
