"The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay." — Tony Hoare
It is impossible in practice to persuade people to pay the same amount for a simple, reliable product that they would pay for a complex, unreliable one with more features. Reliability is a promise, and they have to trust. Features can be demonstrated now, so less trust is involved (or so it appears).
And then the features stop working.
