> OpenAI has massive power to censor what people can reason about with GPT.

This is like saying, the transportation of <city> has massive power to censor where people can travel about within a bus.

GPT is a tool for reasoning, but humans need to be able to reason on their own! and by using multiple tools!

Of course every tool should help and enhance every human, but every tool has its limitations. There is nothing unethical about calling out a tool's limitations and ensuring humans use it accordingly.
