Blue Origin and SpaceX don't need to have that philosophy. Because their owners are having a dick measuring contest and have literal billions to literally burn.
The budget constraints on NASA during the Apollo missions made success a requirement. They couldn't afford to waste money or even look like they are wasting money. Even early tests where NASA rockets were burning and exploding they had to justify to Congress that they were learning.
It helped that the "red scare" kept the public interested in space exploration because it was about beating the Soviet Union.
But when Blue Origin and SpaceX have to answer to just a billionaire, they can get away with failure after failure. It's probably cheaper for them.
