Maybe there's some code that at one point was FOSS in those products, but the products themselves are nor Free.
IMHO a code base that has been forked from a FOSS project cannot be considered FOSS itself even if they keep retrofitting changes back to the original, because you cannot know what is there in the proprietary part. This is specially true if you distribute the derivative product only in binary form.
