I actively reject conspiracy theories on the premise that they’re conspiracy theories. However, I can’t deny that this one is interesting. What if this is actually happening?

Obviously the easiest way to provoke thought within the skeptic is to ask, “If it is within the realm of possibilities for the human race to invent a driver allowing interstellar travel, why shouldn’t an extraterrestrial race also be capable of it?”

I would assume someone would counter with the fact that extraterrestrial life hasn’t been discovered. A question to often revisited. For all we know extraterrestrial life surrounds their inhabited planets with strict ingress and egress policies.

I don't think what the OP is suggesting is necessarily a conspiracy. Institutions are wary of people who risk their credibility with claims that catch a lot of attention but may prove to be false. There's some incentive to make claims that capture a lot of attention and the field doesn't want to lose credibility.

If you think about how some scientists responded to speculation about Oumuamua you can see how they were nervous about speculation that could be sensationalized.

The general idea, yes. I was pigeon-holing to the idea that aliens are carrying it out.
