GitHub Copilot Policy Change Sparks Developer Backlash
A developer post on May 26, 2026 criticizes recent GitHub policy changes and Microsoft’s influence over the platform. The author reports that GitHub announced on March 25, 2026 that, effective April 24, 2026, interaction data from Copilot Free, Pro and Pro+ — including prompts, accepted/rejected suggestions, code snippets and context seen while Copilot is active — will be used by default to train GitHub/Microsoft AI models, with an opt-out buried in settings. The piece also notes GitHub CEO Thomas Dohmke resigned in August 2025 and leadership now reports into Microsoft’s CoreAI organization. The author describes February 2026 outages and long queues for GitHub Actions, alleged proliferation of low-quality AI-generated PRs, and a migration wave toward alternatives such as Codeberg, GitLab and Bitbucket, plus runner alternatives like Depot and Blacksmith.
A major platform (GitHub/Microsoft) changed Copilot data-use policy to default training on user interaction data, affecting developer trust, privacy and potential migrations — a significant policy update with cross-industry implications for data governance and platform reliance.

Key Takeaways & Evidence Grounding
- On March 25, 2026 GitHub announced that starting April 24, 2026, interaction data from Copilot Free, Pro and Pro+ will be used by default to train their AI models.
- An opt-out for Copilot data training exists in settings, but the change is opt-out rather than opt-in.
- GitHub CEO Thomas Dohmke resigned in August 2025; GitHub leadership now reports into Microsoft’s CoreAI organization (per the article).
- Developers reported GitHub Actions outages and long runner queues in February 2026, affecting CI/CD workflows and billing.
- The author reports a migration trend to alternatives (Codeberg, GitLab, Bitbucket) and recommends runner replacements such as Depot and Blacksmith.

GitHub Outages Undercut Microsoft's AI Coding Lead
Microsoft-owned GitHub has faced repeated reliability incidents and a recent security compromise that have eroded its early advantage in AI-assisted coding. Since March, GitHub experienced more than a dozen multi-hour incidents; an employee device compromise exposed roughly 3,800 of GitHub’s internal code libraries. Executive turnover and leadership gaps (including the 2025 departure of CEO Thomas Dohmke and recent retirements/transfers inside Microsoft) coincided with rising competition from tools such as Cursor and Anthropic’s Claude Code. GitHub is moving Copilot to usage-based billing in June and has limited new individual Copilot signups to protect service quality. The outages and pricing changes have prompted some enterprises to evaluate alternatives like GitLab, Bitbucket, and multi-cloud or self-hosted options.
GitHub Will Use Copilot Interactions to Train Models
GitHub (owned by Microsoft) will change its terms so that, from April 24, 2026, user interactions with the Copilot programming assistant may be used to train Microsoft’s AI models. The change applies to Free, Pro and Pro+ accounts; Business and Enterprise plans are initially excluded, as are students/teachers with free Pro access and users who previously opted out of public "Code-Matching." GitHub will collect a range of interaction data (including private repo content during use, Copilot inputs and outputs, cursor context, filenames, navigation patterns and feedback). Microsoft says data will be used internally within its group, authorized staff may view data for model improvement or auditing, and security measures aim to prevent secrets from appearing in training data. Users who do not want their interactions used can opt out via GitHub settings under "Copilot/Features."
GitHub Down to One‑Nine; AI Agents Strain Platforms
A Pragmatic Engineer Pulse argues GitHub’s availability recently fell to roughly one nine (~90%), attributing part of the outage to increased traffic from AI coding agents. The piece questions GitHub’s readiness as the top platform for AI-native development and raises governance concerns—e.g., whether AI tools should auto-add themselves to PRs and commits (noting Claude Code and GitHub Copilot do this, while Codex and OpenCode do not). The newsletter also reports Microsoft pledging to roll back intrusive Copilot integrations and Start menu ads in Windows. Industry items flagged include a major LLM supply-chain compromise (LiteLLM), backlash to Cursor/Composer 2 attribution, and OpenAI shutting down its Sora video product.
