> It's rather offensive to assume that a group of UX professionals decided to take on a massive overhaul just for fun.

I suppose it is human nature to randomly change things (see the other submission about gardening (continuous small changes are different from big changes time to time, still equally annoying)), also a result of the free market, there are too many UX people for coming up new products and make them final.

I bet if architects could change the buildings in minutes and for free, now we all lived in constantly changing (but obviously not improving) buildings.
