"Survivorship bias is the logical error of concentrating on the people or things that 'survived' some process and inadvertently overlooking those that did not because of their lack of visibility." [Wiki]

Sam's saying that very successful companies tend to hit all of these points, in contrast to less successful or unsuccessful companies, which will miss one or more of them.

You don't need to take the post at face value, but if you're claiming this is a result of survivorship bias, then you're arguing that successful companies just happen to have these traits, and they don't actually help the companies succeed. I don't think that's true.
