The argument isn't that some people don't make money, it's that the users and probably the founders are better off building a company that lasts. The users get a great product and the founders get to build and run a profitable business. Part of their argument (which is referenced but not explained in the post) is that it's not personally fulfilling to get rich and retire early but rather to continue to build.
Reading the article, you can certainly argue that Dopplr didn't have the adoption curve they hoped for. They get money, they get to do something new (one founder's a partner at BERG London, who are pretty kick-ass).
OK, bad day for Nokia. Dopplr's fault? Nope.
