It's a little like telling a construction worker "You don't need a super-powerful 'jackhammer' to do your work. A simple claw hammer is all you actually need."
Well... sure, that's definitely true if you're building a house.
But you might have a problem ripping up a sidewalk...
There are plenty of companies building houses, and plenty who are working with concrete! Neither one of them are "the big kids."
They're not even necessarily different-size markets, either -- you can make a lot of money building houses or making sidewalks -- it's just that different problems require different solutions, and different software companies are going to have different challenges to the problem of "get bigger."
