Microsoft's C/C++ Extension Breaks VS Code Forks, Sparks Antitrust Concerns

Microsoft's recent update to its Visual Studio Code C/C++ extension has broken compatibility with derivative products like VS Codium and Cursor, prompting outrage from developers. The move is seen as anti-competitive, as Microsoft restricts its extension's use outside its own products while simultaneously promoting its own AI coding assistant, Copilot. Developers have filed complaints with the US Federal Trade Commission, alleging unfair competition through bundling Copilot, blocking rivals like Cursor, and locking users into its AI ecosystem. Cursor is reportedly transitioning to open-source alternatives.
