Any projects which want to use Hush code from now on will need to be licensed as GPLv3 or we will send the lawyers: https://www.softwarefreedom.org/ Notably, Komodo (KMD) is licensed as GPLv2 and is no longer compatible to receive code changes, without causing legal issues. MIT projects, such as Zcash, also cannot pull in changes from the Hush Full Node without permission from The Hush Developers, which may in some circumstances grant an MIT license on a case-by-case basis.
