Perforce (the product) doesn't really scale sufficiently for the Googles/Amazons/Microsofts of the world, sadly.

I think they've all moved to custom forks/implementations due to the insane SPOF that Perforce servers are (and their hardware requirements). But up til that point, heck yeah!

Well, Perforce in its default state may not scale sufficiently, but at least two of the companies on that list have managed to make it work (presumably with a lot of investment, though). :)

I didn't know Amazon was using Perforce. I interviewed someone from Amazon recently and he indicated they were on Git for most things now.

Amazon has phased out perforce a year ago. There is very little left, most repositories (perforce, svn, etc) were migrated to git repositories.
