I feel like there's several industries that are practically computer science yet don't utilize open source effectively. Data science is definitely one, but the video game industry definitely comes to mind.

You could argue game engines are notoriously complex, but the Linux kernel would like a word.

Isn't the main driver for this that data science is new enough that companies don't know where the competitive edge is? And by default, the data is confidential.

Software modules are commoditized at this point. Just pick building blocks and spend all your time on tying them together in ever increasing complexity. Curl (and similar tools) clearly is a commodity, but that web scraper that gives you the ability to compare Apple to Orange in real-time, that may be what gives you the edge. And the first-order analysis of said data is even more likely to be what lifts you above the competition.
