The "disruption" companies arent innovative, that is just the facade, it's a capital strategy where you burn capital (and fuck the workers as an optional bonus) in order to undercut and bankrupt the competition to then provide the same service at an even higher profit margin (and cost to the consumers).
It works bcs the "innovative" angle is hard on regulatory agencies (to prove unjust predatory pricing), and the capital financing the companies initial loss isn't as bad with high company valuations (due to promised/predicted future profits, and due to financial markets providing liquidity so that investors aren't locked in/selling at a loss before the whole strategy pans out).
The goal of capitalism isn't to provide a good product.
