Now, Microsoft has moved WinUI's mainline development entirely into public view on GitHub — not as an announcement, but as an act: every commit, pull request, and bug fix visible to anyone who cares to look. It is a rare moment when a technology company chooses accountability over narrative, inviting the world to watch whether its intentions and its engineering actually converge.
