I don't understand what you mean by "suppressed", I've seen countless mentions of the lab theories on HN, other social media, and news sites. These theories have been around from the start and have always been considered less likely than the wet market hypothesis, as the linked articles also argue. But even if you were right, you should never believe a theory just because it cannot be easily refuted or because you feel it is suppressed. It's trivial to come up with theories that are hard to refute or cannot be falsified at all. Theories can also be suppressed for all kinds of reasons that have no bearing on their truth. If there is a lack of positive evidence for a theory you need to remain agnostic or at the very least try to obtain realistic probability estimates.
Firstly, I would prefer if you didn't dictate what I should believe in and what I shouldn't. I'm fully capable of analysing the information that I have and form my own opinion and it's alright even if it turns out to be wrong.
Secondly, it was suppressed in the way that news media and Twitterati were labelling everyone considering this theory as a possibility to be racist because some racists they know also shared the same views.
