Keep in mind that's the model that worked when unit economics made it possible to capture outsized profits.

Think of Facebook, their incremental infrastructure costs for delivering messaging and feed services to an additional user are negligible (significantly less than a dollar per quarter) compared to the revenue they're making per user (dozens of dollars per quarter). In that cost model, grow at all costs then monetize makes sense.

For Uber, Lyft, and WeWork, there are no economies of scale (ignoring the fixed R&D costs). Twice the amount of rides given will have twice the driver costs, and the drivers will always petition to get a bigger slice of the pie.
