I said I don't disagree given the assumptions stated.
I do disagree with the unqualified assertion that "compromising on people is one of the worst mistakes a technology company can make." Culture is a broad term that covers a lot of things. There are important and unimportant aspects. If you reject a person because they can't work productively in your org, that's one thing. If you reject them because they'd rather go home to their family rather than participate in your after-work Starcraft sessions, that's another. Both can be considered culture, but only one is actually important to the working environment. Furthermore, marking it as the "worst mistake" makes the assumption that compromising on culture is necessarily destructive, which its not. Again, it really depends on which points you're compromising on.
