@emaste @mwl I agree the statement that FreeBSD is "slopware" is misleading - and it dilutes the term to the point of being nearly meaningless. But the "policy" linked is very much relevant, and I suspect the two commits may - in their simplicity - fall on different sides of the "line in the sand" that distinguishes between what is, and what isn't, acceptable. It could also be a matter of labelling in this case (making both commits fall on the same side of that line).
Whether code from external projects (llvm, zfs) should be subject to the same standards as core itself is a matter of some debate; the cost could be prohibitive if they are tested the same - but if they are not, then can we be sure the licensing holds?
And in the end, who decides if a piece of code is significant enough to be copyrightable, and therefore possible to apply a license to? IANAL, and neither are other contributors likely to be, and that is kind of the point. And even if we all were, I'm sure we'd disagree on all kinds of things anyway :)
