I suppose, if you want to blame them for making use of on open-source code released by a third-party software vendor that was happy enough to release it under the GPLv2, but not happy to allow arbitrary changes to the license terms controlled by the whims of the FSF in rewriting licenses in the future, and who has no interest in relicensing now under the GPLv3, with or without an "or any later" clause.

If they had left in the 'or later' clause they could still use it under GPLv2, just not _limit_ it to GPLv2, which is what the 'third-party software vendor' decided to do.

If they had left in the 'or later' clause, they couldn't use software from the third-party supplier, who only licensed under GPLv2 without the 'or later' clause.

If you are distributing someone else's software (even as part of your own work), you are restricted by the terms of the license they've given you. If that's GPLv2-only, you can't distribute a work incorporating their work as GPLv2-or-later.

With 'they' I was referring to the 'third-party' who were the ones which licenced without the 'or later' to begin with.
