OpenPGP in Rust: the Sequoia project

It all depends on whether you think the point is to improve software freedom or to give firms ammunition to create fear, uncertainty, and doubt. I'm firmly in the camp of the GPLv3. It addresses problems which arose when billions of dollars of revenues were tied to new ecosystems and methods were developed by their corporate fiefs outside the spirit of the GPLv2 to control those ecosystems, and their fury that they would lose those unprincipled mechanisms back to users.
