What an egregious mistake. "exhibits a pattern consistent with an individual operator using the repository as a working scratchpad or synchronization mechanism rather than a curated project repository" - isn't is git 101 to not put creds in git? What pattern do they think this is consistent with?
They're not defending it as an established workflow pattern or some kind of best practice.
The usage of "exhibit a pattern consistent with..." is just describing what it looks like the repository was used for. i.e. it's not a set of government sourcecode for an internal project, it's not something indicative of intentionally leaking large amounts of data, etc.
