Ah, this sheds light on the silence around the Windsurf acquisition:

OpenAI and Microsoft are at a standoff over the terms of the startup’s $3 billion acquisition of the coding startup Windsurf, the people said. Microsoft currently has access to all of OpenAI’s IP, according to their agreement. It offers its own AI coding product, GitHub Copilot, that competes with OpenAI. OpenAI doesn’t want Microsoft to have access to Windsurf’s intellectual property.
