The conspiracy is to cover up the accident, and to deny that any unsavory/illegal research was going on. Some people go even further and think it was intentionally leaked. I wouldn't necessarily go that far. But yes, one could believe in the accident and think everyone else is just honestly ignorant about the nature of the accident. This turned political for multiple reasons, chief among them that Trump said there was a lab leak. The media could not admit anything he said was legit, because they wanted him out. They were also against "rushed vaccines" until a new president was in, then they wanted to force that injection on everyone whether they needed it or not.
