You are right - information, money, influence - all of there are types of value that humans are competing for. It’s the war of all centuries, simply taking different forms. 

In fact, monopolisation effect is also part of how nature works. Strong get stronger, weak get weaker.  Rich get richer, poor stay poor.  The biggest puppy gets all the milk. In isolated environment this tendency is inevitable. We also know that we can’t simply force redistribution - it would disproportionally benefit underperformers and destroy excellence. In social structures history we already went through disasters of forced redistribution. Equality of outcome has got to be the most stupid and destructive idea humans ever conceived  

Luckily natural ecosystems are not isolated. They change. Change of environment is the absolute best way of bringing about a long term equality of opportunity. No matter how big a locust plague is, it will collapse at some point - due to some natural change, like a huge storm, drought or hurricane. Tech world monopolies can be a lot more resilient than locust, though and the hurricane that would change the environment has to be purposefully built. Not a destructive hurricane, mind you, but a hurricane of new ideas and initiatives that changes the tech landscape enough to subdue tech monopolies or force them to adapt and become cooperative players.
