Regulators are political amalgamations; as we've seen recently with Alzheimers and this drug, those entities can be quite powerful.
I don’t see the purpose of complaining about it in a situation where the institutions are working as intended (and desired).
So: there's a purpose in complaining about it and hoping that regulator and regulation can be improved.
Keep in mind 90% of drugs fail clinical trials. The situation cannot be THAT bad.
