I've directed Krav to some reliable sources which I hope he will use to improve the article. In the meantime, it seems reasonable to balance the two competing perspectives on kapap by including both external references, so I have done so. I think the issue is partially a question of balance. The entire article needs to be better sourced, and as that is done, hopefully the need for using either external link as a citation will be alleviated. They are borderline even as external links, especially the promotional New Jersey one that is being maintained and protected, if we are to believe Krav. I haven't been here long enough to know. I believe Krav's concern is also that the perspective on the subject reflected in the article itself is partial to this commercial interest and advocates their view on kapap. Again, the best way to address that is to rewrite the article using citations to reliable sources.
