  Is that true?  Or is it just a hypothetical example?

Tahoe-LAFS, currently at version 1.10, is dual licensed, under GPLv2
or any later version, and the other license mentioned above.[1] The
combination of GPLv2+ and the secondary license probably achieves
consequences other than those the project intends, but at any rate
there is no doubt that the project is copylefted free software.
