Personally, I love the UFO stuff and would like nothing more than to learn aliens are visiting us. But I think it's far more likely that it's all part of a government disinformation campaign, mostly based on the fact that Lue Elizondo (aka Lue Anon) is a career disinformation asset, and the entire saga has played out exactly as you'd expect a disinformation campaign to go. The only "data" we have on UAPs comes from military "leaks" and second-hand reports. The paradox of the UFO community is that on one hand, they accuse the government of lying to us for 70 years, but on the other hand, they point to evidence "released" (selectively leaked) by the government as incontrovertible proof of "the phenomenon."
As for Avi Loeb (first author of the linked paper), I have great respect for him and anyone who would keep such an open mind, but I have to admit he's also a bit of a charlatan huckster. I remain curious to see the results of his Galileo project, but I'm skeptical they'll be able to find some tiny fragments of a meteor that crashed into the Pacific ocean a few years ago. And if they do find such fragments, and claim that they're part of an alien ship, I'll be even more skeptical.
