How does "Leveraging a monopoly to destroy technological progress" not fall under some antitrust laws? Is it just because Craigslist is free? I definitely feel the consumer is potentially losing out due to Craigslist's monopolistic practices.
CL isn't US Steel. I doubt Craigslist even has a straight 40% of rental market share. But for urban 20-somethings looking for cheap living situations and roommates? It feels like it has 95% market share. At least in Portland.
This is all theorycraft though. If anyone had hard numbers on CL's market share for rentals I'd love to see them!
