You're not really engaging with your parent's point, which is about misinformation.
Would it be OK if Twitter allowed misinformation about the miltary operations in the Ukraine to run rampant? Would it be OK if Twitter censored pro-Ukranians (because they share a lot of misinformation)?
IMO yes it would be totally OK if Twitter allowed misinformation (on almost any topic) to run rampant. How did we get into the position of expecting a platform that explicitly gives microphones to a huge variety of people to then turn around and police those people to make sure they're not saying false things? What happened to "trust nothing you hear and only half of what you read"? Determining what is true and what is false is not the job of the platform, but the reader.
