Exactly what I was thinking reading this article. Perhaps Oumuamua is a piece of evidence that fits this theory, but, is it really the first one? If it is the first one, it hardly proves the theory. At this point (from what I can see) we have a sample size of 1 (Oumuamua). Now, we also haven't been watching for very long (10 years or so where we could track this sized object) and aren't watching too much of the sky, but, this still doesn't prove anything.
