Your reasoning suggests that if the people who built Yo were not building Yo, that they might be out there curing the world's diseases. See the flaw there?
If the people who built Yo had been curing the world's diseases instead of building Yo, then everyone would still be stuck with giving each other Facebook pokes, and would therefore be too demoralized and disconnected to complete the task.
The article simply sounds like sour grapes. If something as simple and stupid as Yo can get funded for $X, then why hasn't my worthy and interesting project been funded for $Y ? Obviously, the developer of Yo is to blame for finding a big pile of money curated by fools and taking it?
It is pointless to question why Yo exists. It is far more useful to ask why nearly everyone capable of accomplishing great things has to go beg shrewd financiers and capricious morons (depending on whether or not they give you anything) for the money required to attempt one, or languish under the direction of someone else as an employee until finally saving enough to try.
And the answer is that life is not fair. A plutocracy is not a meritocracy. If you don't like it, be born rich or win big at business roulette, and then invest only in worthy things.
