The term „license incompatibility” is used in situations where you cannot use of a different license in a single program. Usual example is incompatibility between GPL and anything that’s not a subset of GPL.

The situation here is different: it’s about distribution, and it’s up to you, the distributor, to decide whether you want to include restrictively licensed software or not. With license incompatibility, you don’t get that choice: you just cannot legally distribute it.
