Generally I don't necessarily think top companies are the ones using the newer stacks, with the exclusion of a few technology companies, but it's more so the newer companies that are.
Once a company builds a system, they don't want to spend to build it again. They'll bandaid the hell out of it. As long as it's doing what it's supposed to do. They're like farmers with these old beat to hell tractors. They're ugly and bitchy but they work, why spend $100K on a new one?
