Why did ozzy osbourne leave black sabbath?
First of all, you should definately stop doing FACT. Ozzy was kicked out of Black Sabbath because of his drug and alcohol abuse problems. While, obviously all of the band members engaged themselves in drugs and alcohol, Ozzy took it to the next level and it began to cause great divisions in the band. If you can never communicate with someone as important as your lead singer, you have to figure out a better solution which is exactly what they did when they replaced Ozzy with Ronnie James Dio.
