I wonder if there is some survivor bias there. I'm sure there must be cases where everything went wrong but nobody writes about it.

Wouldn't survivor bias explain who BigCo X can be found using whatever questionable choice they originally made, but not explain why lots of BigCos have changed their practices.

This might explain Facebook and PHP, but it doesn't explain the stuff mentioned in the previous comment.
