Why do you assume that focusing on design in a startup means that the startup will "solve zero problems"? Admittedly, I'm biased (my startup is in the current batch of The Designer Fund), but the fund is very focused not on "prettiness", but usability and interfaces that work and convert.
I think it's rather unfair that you look at the graphic which is celebrating companies with designers and then rant about design making shitty products. Design is CRUCIAL to a good product, because design isn't "prettiness", it's how people use it and how it works.
Which of those infographic cards would you call shitty? And why?
