This is a case where you have to be careful about cause-effect order. I assume that Tiwanese people that are heavily opposed to China are more likely to avoid tiktok. But of course, it’s been shown that tiktok tends to show more pro-China “content” as well, and likely influences the opinions of its users.
Whatever anyone China-affiliated says they’re not doing, it’s a safe bet that’s exactly what they’re doing.
I’m not going to push any conspiracy theories, but I believe the strongest evidence pointing towards Covid-19 originating in a lab is the Chinese government insisting that it didn’t, while prohibiting anyone not under their control from investigating. That doesn’t mean it did originate from a lab, but if anything, that’s what it points to. To be explicit: My impression is that, currently, most available evidence points towards natural origins. However the Chinese government has done its best to convince me otherwise.
