Centralized open source projects — where a single organization (the “steward”) funds development, employs core maintainers, and sets the roadmap — are assumed to have different communication dynamics than community-driven projects. The steward's employees have authority that volunteer contributors don't, and this power asymmetry should be visible in how they write: more directive language, different hedging patterns, distinct rhetorical strategies.
Gaughan, Shaw, and Gergle (arXiv:2603.12571) test this assumption on three Wikimedia Foundation features and find the opposite. Using principal component analysis on linguistic features extracted from repository discussions, they find no identifiable differences in the linguistic style of WMF-affiliated contributors and external contributors. The people who are paid to direct the project don't write like people directing a project.
Two explanations are proposed. First, stewards influence development through feature selection — choosing which features to build — rather than through conversational dominance within a feature's development. The authority is exercised at the portfolio level (what gets built) rather than the discussion level (how it's built). Second, centralized governance may create common communication norms that both insiders and outsiders adopt, producing convergence rather than hierarchy.
The finding matters for understanding how power operates in collaborative software development. If hierarchical authority doesn't manifest linguistically, then studies that use communication patterns to infer governance structure will miss centralized control entirely. The steward's influence is real — they choose the features, hire the developers, allocate the resources — but it's invisible in the text. The hierarchy exists in the selection of what to discuss, not in how the discussion proceeds.
