As he is on supervised release from a prison sentence, he does not currently have the full set of constitutional rights. The government can place nearly arbitrary restrictions on his life until his sentence is complete. If he disagrees with the restrictions, he is free to instead return to prison to finish his sentence behind bars. Or he can agree with the restrictions for the ~3 years he has left on his sentence and afterwards be free of them. To be clear, I do not necessarily agree with any of this, or think it's a good idea, but it is all settled law. Despite what it sounds like, this is not a violation of his constitutional rights, any more than preventing him from recording songs in prison is.
