This is a good read. I think the problem is, it takes actual work to do things "right" these days, and also companies can get too big to change the course of the ship in a different direction. People also like to do what they're comfortable with and what's subsequently easier and faster for them. I just like when people take the time to look at something differently like you have here—there is nothing wrong with server side calls, especially when done cleverly and with caching etc.
