I'm not defending the TGPPL, I'm just picking at it from a different
The license explicitly allows me to distribute my derivative work
without licensing it under the TGPPL (as long as I can magically
ensure that after a period of 12 month the TGPPL will apply). That
part is worded clearly. What isn't clear at all is under which other
license I would be able to license my derivative work for that 12
months period. Apparently anything would go, as long as these other
license terms terminate within the timeframe.
Of course, a license that only behaves like a permissive open source
license for a period of 12 month would be an oxymoron.
