It's not a symmetric bias. If someone selling you tobacco or ad spam tells you it's safe, one could reasonably be skeptical. If that same person voices specific concerns, it's more notable for coming from them.
Imagine a company that gatekeeps a language feature, and they are staffed with Creationists or Scientologists. Is it notable if they define certain output as dangerous? No. Should you be skeptical? Yes. It's the same if they are staffed with Wokeists. In both cases they are defining what's "dangerous" according to their religion/ideology.
