The initial paper and comments by some experts convinced me that there is a strong chance that this is a probe. It seemed plausible based on my limited understanding of Physics. (Moment of Inertia, Stresses etc.)
But then a paper[1] was released claiming this to be a comet. I so wanted my original belief to be true(because it was more exciting!) I considered the possibility that their [2]model wasn't accurate. I was even willing to entertain the idea of cover-up just because it didn't align with what I wanted to be true!

[2]A recent study claims that it was indeed the case and the probe is more likely to not be a comet. https://www.quantamagazine.org/interstellar-comet-oumuamua-m...
