For what it’s worth, “move fast and break things“ was a Facebook thing. The idea was that if people couldn’t post pictures of their dogs for an hour or two, that was a tradeoff they were willing to make for c faster feature development.
Many, if not most, Tech companies don’t subscribe to it.
Also it was "break things for a few 1000 people while the other billion users have no idea because everything you deployed is behind feature flags." It can't apply to physical products.
I think you can argue that Facebook should have outgrown this as it became a major way that people communicate. I worked at a lot of different Silicon Valley companies over the last few decades, and they would all be appalled by someone advocating to “move fast and break things”.
