      6. Each time you redistribute the Program (or any work based on
      the Program), the recipient automatically receives a license
      from the original licensor to copy, distribute or modify the
      Program subject to these terms and conditions.

If it were so and any of them infringes on the license, then all
downstream users would have their licenses at risk.  This situation
would be akin to sub-licensing.  But this is not how the GPL works.
