I'm not sure this is completely right. The GPL explicitly says one doesn't
have to agree to the GPL to use the software. The GPL only comes into
affect when distribution is involved. So challenging the legitimacy of the
GPL in court (which certainly has happened in Germany) wouldn't prevent one
from using the GPL software. Only from distributing it.
