In 1993, Prince changed his name to an unpronounceable symbol because he was unhappy with his contract with Warner Bros.

The statement is true because in 1993, Prince did indeed change his name to an unpronounceable symbol as a form of protest against his record contract with Warner Bros. The symbol was a combination of the male and female gender symbols, and he referred to it as "Love Symbol #2." By changing his name to a symbol, Prince aimed to regain control over his music and artistic freedom, as he felt restricted by the terms and conditions of his contract.
