Hi everyone,

As you all know, we're working with the FSF to enable one-way compatibility from BY-SA 4.0 to the GPLv3. All signs point to this moving forward, and we are preparing for an announcement in early May.

As we were conducting the final analysis, we discovered that I failed to point out one relatively significant point during the public discussion.

When BY-SA content is adapted into GPL projects, downstream users will be able to look to the conditions of the GPL to satisfy their obligations to the BY-SA licensor. GPLv3 does not contain a clause that parallels the attribution removal clause in BY-SA 4.0.

This point was raised during the compatibility process for the Free Art License on this mailing list, but we thought it was worth calling it out again in the GPLv3 context.

best,

Sarah
