Earlier quoted context omitted.
Remind me of their narrative again? They say that > "Trump did not explicitly tell people to 'storm' or 'breach' or 'break into' the [US] Capitol." and included the reasoning that > the president called on supporters to “peacefully and patriotically” march or walk to the Capitol ...but wait, their far-left narrative! Why didn't they omit those references and reasoning?! https://www.snopes.com/fact-check/trump-tell-su…
Almost all these “fact checkers” exposed themselves on the lab leak theory which they had to redact after 1.5 years. Relying on any of them as a source of “truth” is asking for trouble. They are more of a narrative check.
When Snopes says "the lab leak theory isn't real", they're basing it off of scientific research carried out early in the pandemic which claimed that the virus didn't look engineered. That is, effectively, an expert opinion - something close to truth but still subject to change should new information come to light. It's entirely reasonable for a fact checker to rely on that information at that time, as well as change their opinion in response to new information.
