An answer like "for some reason manufacturers only use garishly bright LEDs" is (too) true, but not really about it being digital (c'mon eink!), while answer like "I find analog clocks to be prettier/more elegant" can be true but is clearly subjective.

I've just never understood the desire to have a clock that doesn't tell the time but instead shows some foreign representation of the common understanding of time (and not too precisely at that). That doesn't mean there is no argument I'd find persuasive, I've just not heard it yet. Care to share?
