It's true that innovation trumps economy of scale, but that's because economy of scale doesn't really apply to software; all software is instantly scalable to 100% of humans at virtually 0 cost, more or less.
But the software giants have something up their sleeve that no startups have: economies of scope. Look at Shazam/SoundHound. Google has released Play SoundSearch which leverages all of their internal AI research + advanced computational and human resources that aren't available to the public. In effect, a megacorp can replace an entire company by saying "Let's throw 15 engineers on it for a year and see what happens." And if a startup pops up that seems promising? They buy it out, adding it to their trophy wall of innovations they can leverage. And megacorp employees can easily stand on the shoulders of giants; instead of stackoverflow, megacorp employees can search through massive archives of top-notch, fully-working code that was designed by some of the best engineers on Earth.
More and more, it takes something truly amazing for a startup to grow enough to compete with a megacorp. Not only does your technology have to be profound, but you need to withstand aggressive buyout deals from several megacorps.
