I think it'd be an interesting startup idea to decentralized all the monolithic services. Create an Uber for City X(ie Uber for London, Uber for Chicago, etc.). Allow the municipalities to run those services. And do the same for Airbnb, Yelp, Google, Facebook etc.
I love this idea. I use to work for a "The WordPress of $INDUSTRY" startup and letting people rum their own thing and self brand was very fulfilling work. I think it's important to protect specific categories of small businesses (or simply markets that shouldn't need to be overly centralized) from the growth of underhanded heavy hitting centralized monopolies. I call it AmaZoning when a large player comes in and says "I'm the new middle man".
