I for one am going through quite a culture shock. I always assumed the nature of FOSS software made it immune to be confined within the policies of nations; I guess if one day the government of USA starts to think that its a security concers for china to use and contribute to core opensource software created by its citizens or based in their boundaries, they might strongarm FOSS communities and projects to make their software exclude them in someway or worse declare GPL software a threat to national security.
And it’s why people stress to death that documenting is important. Even if you may not have time to review every single code, it wouldn’t hurt to leave footnotes as to where someone could take said code to pick up from where it left off.
If you leave somebody with nothing then it’s dead code.
