The main problem is the "mega" part which is mostly a side-effect of seeking profit without wondering whether that's the best way to structure an organization that seeks to "connect everyone" or "organize the world's knowledge". Neither of those missions should be subordinate to profit motives but at the moment the companies that claim it's their mission to "organize the world's knowledge" or to "connect everyone" are actually doing something else entirely: trying to make as much money as possible.
