There have also been Apache v2-licensed projects that have not used CLAs and gone proprietary. The risk of a proprietary fork by Element is not changing as a result of this, and actually the risk of a proprietary fork by anyone else (that includes post-relicense changes) goes away. I too would prefer AGPLv3 with no CLA, but that doesn't seem like it's going to happen at the moment, and this seems like a step in the right direction.
