Believe it or not that is how companies use to operate till recently. Most companies didn't even have guides/books/web pages on culture.
I know, know, know to attract top talent you have to make a place look more than just a job like your on some epic moral spiritual journey.
Now I read this stuff and it sounds like a great mission statement that is being forced on to the employees in some disingenuous way to make people "passionately" pump out work overtime while blindly believing whatever the company says.
The biggest irony out of all the culture "guides/books/page" is that they often tout or say how much they are for diversity (I know stripe doesn't in this case). It seems wrong to say you are for diversity when you are requiring people to think and act a certain way because you think its optimal.
