This attitude is (imho) a major problem in research/academia. If you've done research into something you should report it even if the results were unclear, ambiguous, or non-existent. For one it lets people know if this is a fruitful avenue to pursue and/or whether further study is warranted. It can thus reduce unnecessary repetition of effort. Furthermore, making the findings and methodology public enables people to use it as a starting point for other studies, perhaps varying the methodology or asking different questions on related topics.
Though I think @cypherpunks01 and @WalterSear are likely right about this particular article/page.
