That's incredibly reductive. Literally just follow the data, there was some dystopian censoring going on under the guise of racism. A facility that literally worked on the virus, where the virus started, destroyed evidence and refused independent investigation. If it wasn't a political issue people would have unanimously freaked out.

Instead, we still don't know exactly how this one happened, which would be amazing if it could help stop this happening again.

Low confidence means they have supporting data but it isn't a high degree of confidence. I have a pen and paper, and a written letter is near me. There is a low level of confidence I wrote it.

Edit: didn't the FBI say the same with moderate confidence?

Why is it conspiracy!? The largest pandemic in recent history and we still don't know the source, why rule this out?
