This is (was?) called the Java Trap: https://www.gnu.org/philosophy/java-trap.html

    If some of a program's dependencies are nonfree, this means that all
    or part of the program is unable to run in an entirely free system—it
    is unusable in the Free World. Sure, we could redistribute the program
    and have copies on our machines, but that's not much good if it won't
    run. That program is free software, but it is effectively shackled by
    its nonfree dependencies.
