I note that article seems quite biased against Loeb. For example, they cite USA Today strongly criticizing him, which is not a reputable source in this debate. Wikipedia also doesn't mention that many other astrophysicists think that his 'Oumuamua theory is unlikely but not crazy. They only cite very negative criticism, but not the many more neutral responses. They also don't mention that he is far from the only one believing that 'Oumuamua appears to have a highly unusual shape. Wikipedia tries to paint him in the worst light possible.
