Mediabiasfactcheck has been repeatedly caught in lies and distortion of truth. Repeated claims that have proven false about Covid alone are enough to quit using them. Takes going to court to get them to correct lies they publish. It is atotally discredited, self-styled ‘fact-checker' site that has been served with a ‘cease and desist' legal notice for publishing unsubstantiated and defamatory claims against Principia Scientific International (PSI).
You have been misled by poor sources. We have never been taken to court nor received a cease and desist from PSI. Nor changed their review. He is lying. Further, we rely on the consensus of science regarding Covid and all science. If you don't agree with the consensus, that doesn't mean the consensus is wrong.
