Elon Musk said he had a “good conversation” with Apple CEO Tim Cook and “resolved the misunderstanding” about his claim that Twitter could be removed from the App Store, just days after launching a scathing attack on the world’s most valuable tech company.

Musk said in a tweet on Wednesday that “Tim was clear that Apple never considered” removing Twitter from the App Store, calling it a “misunderstanding.”

Musk, who paid $44 billion for Twitter last month, also thanked Cook for “taking me round Apple’s beautiful HQ” and shared a video from Apple Park.

The alteration comes after the billionaire entrepreneur accused Apple on Monday of threatening to “withhold Twitter from its App Store” without explaining why, and censured the iPhone maker for limiting advertising on the platform, writing: “Do they hate free speech in America?”

The CEO of Tesla and SpaceX also worried about Apple’s “in-app purchase” policy, which gives the company a 15-30% cut of digital purchases made on the iPhone, and claimed that the company abuses its market power.

Musk has previously stated that he intends to transition Twitter away from relying on advertising revenues – from which Apple takes no cut – and toward more subscription revenues, from which Apple will take a cut.
