This is patently false, don't spread rumors. Voluntarily delaying release at the request of the government is not the same as imposing export controls.
I hesitate to call anything "voluntary" when a competitor company was declared a domestic supply chain risk for refusing to do everything the administration requested.
By saying it’s false you are also spreading a rumor that OpenAI is goated by us defense. The reality is we don’t know the truth. But since we are spouting off rumors: Government could have given them a national security letter that says, “send all of your prompts and response data to a mirror run by NSA”
