Thomas Dohmke, the CEO of GitHub, is set to step down after approximately four years at the helm. His resignation marks a significant shift for the platform, which will lose its autonomy as it transitions into Microsoft’s CoreAI division. Dohmke has indicated plans to start a new venture, returning to his entrepreneurial roots. The transition raises questions about GitHub’s open-source stability and investment in cloud services as it aligns more closely with Microsoft’s AI-driven strategy.
