The hard drive that you have is pulled directly from the GitLab instance at gitlab.aggregateiq.com. That would have been data held by AggregateIQ. However, they did incorporate a lot of scripting and software that is available on the open Internet.
I think the answer to your question is that this is internal AggregateIQ data. The overall philosophical answer is that anybody in the world could have accessed it, both because it was open and exposed on AIQ's side, and because they built it using software, primarily frameworks, that are available to the public. It's a bifurcated answer.
