> You can ban harassing behaviour without banning open discussions.
You can. But you'll still have people screaming about how they were actually silenced for their political views. Which is exactly the situation we have today.
Banning harassing behaviour doesn't necessarily entail banning people. You can also make the reasons for suppression publicly visible and so auditable to expose any such lies.
More transparent systems with less suppression or banning are clearly possible, but commercial entities don't want to hold themselves to strict rules which is why they keep the rules and processes opaque. This same trend is seen in both social media and app stores.
