This will be some interesting competition for IDA Pro, Binary Ninja (binja), and Hopper Disassembler. People with access to GHIDRA have been avoiding it because they prefer to develop skills with software that can be used at all employers, but soon that thinking will favor GHIDRA. IDA Pro is a few thousand dollars, and the other choices are a few hundred dollars.
This question has been explained a bit in a blog post by the pentagon [1]:
> While all of the work done by Federal employees remains in the public domain with no restrictions, public contributors enjoy the protections of widely adopted free and open source licenses. As projects mature, the aggregate work — with all the patches, bug fixes, and additional features — will fall under the license associated with the project.
