IMO it is actually worse than unregulated because it actively suppresses people that e.g. talk about gender diversity, criticise Trump and his first lady Elon, push back on hate speech…
While in theory you are right for any somewhat neutral and sane platform, Twitter is definitely beyond that. It actively promotes the spreading of hate, lies and misinformation while actively prohibiting the converse. As such diversity is severly hampered (of course it’s not 100% one-sided but it is very much apparent imo). Twitter is not a free platform, no matter how often Elon says so. In fact, when he says “free” the only freedom he thinks of is his own to blabber whatever he wants and ban everyone criticising him.
