In early days of Airbnb, they were entering market with bigger competitors like HomeAway and Couchserfing. In those days their breakfast service was one of the biggest differentiators. They focused on small niche of the market. Once they outgrew that niche, they dropped the breakfast option. It makes nice narrative, when Brian Chesky says how naive they were in the beginning to insist on breakfast. But actually it was well executed entrance into a market - focus on small niche, until you have product market fit and then drop the features that prevent from extending from that niche.
