This is definitely truth to this. Running your own infrastructure is not popular, much less "flashy". It is capital intensive. Some businesses explicitly avoid capital investment worsened by some localities having "fun" tax/accounting rules for capital assets. At some point, using an external service provider is a better tradeoff for the business decisions. The other major aspect is few basically run small scale infrastructure like people once did even just a decade ago, so the base knowledge and opportunity to learn is not what it once was, which is an overall technology industry conundrum.
