I work at a Navy research center that's 3000+ employee strong and feeds all of DoD (we're a working capital fund, meaning we take customers to fund ourselves). In four years here, I've worked projects sponsored by Air Force, DHS/CBP, Navy, Marines, and two three letter agencies. There was no general involved in any of them, and I don't know any projects by coworkers that involved acquisition of technology. As for my projects, all except one still still in R&D have transitioned into production systems. All involve OSS to some degree. One was a design for a COTS multi source information fusion system meant to be deployed in the cloud and has all the open source tech there you'd expect, NiFi, Kafka, Spark, etc. My current project is a combination of us (correlation) and two contractors (separately IT and predictive models). Again, it's all the OSS and tech you'd expect to find in a real time analytics/tipping system and CI/CD pipeline/orchestration.
I bring up my experience not to say you're wrong but to show there are other avenues it comes in. There are lots of research labs, and researchers aren't about buying software from contractors.
