Sublicensing can only create additional restrictions on top of the existing conditions inside the license. All open source licenses require at minimum that distribution provides attribution and the original copyright notice. License like GPL has additional conditions.

The theory is that licensees of exclusive licensees are assumed to have the control/authority similar to that of the author. Nonexclusive licensees are not assumed to be granted such a monopoly by the licensor.
