Last month, the company behind music streaming app Musi sued Apple for breach of contract, following the removal of its app from the App Store. Musi hoped for a swift reinstatement through a preliminary injunction, but Apple believes the court should deny the request. The tech giant argues that the delisting is allowed under its developer contract, stressing that the removal was not an impulsive decision.
I assume that Musi is a YouTube client that repsects user rights.
