It's true that it doesn't so much sense in digital. Two reasons exist - mobile devices and aesthetics. Many people regard text set to justified as something luxurious or "high". The problem is that justified text is hard - it needs human intervention and proper settings and composer engine. Basically you can properly do it only in LaTeX with some plugins and indesign. The way it is handled in browsers must be computationally efficient so browsers do it in half assed way. Dont use hyphenation in digital except where stuff would overflow.
