Free speech, like everything else, needs regulations to work. This is hard, and maybe impossible to do well, but the alternative (no regulations) leads to chaos. Not just chaos of discussion: chaos of society.
The only way to stop bots, or at least lessen their impact, would be to make verification via ID (passport, drivers license, etc) mandatory. But that opens up a whole other can of worms.
Another thing i noticed is, that many people don't seem to know what "free speech" actually is. Maybe it's different in the US. I can only speak for the German version of it. It's to protect you from prosecution by the government. It is not a free ticket to attack others and it doesn't protect from criticism.
The problem Twitter emphasizes is that free speech and anonymity do not work at scale. Pre-internet, speech always had a degree of accountability because you know who's saying what. Now, you don't know if you're engaging with with an ad team, a bot-net, a trained cohort in another country, or just your dumb neighbor's political views.
The reasonable netizen has to assume the majority of what you see online is manipulated and fake. We can't fairly say the worst parts of twitter are purely a failure of free speech.
That being said, its an age old battle which system is better: one that is free, open, optional, and sometimes gets it wrong or one that is closed, managed, unavoidable, and can't be reviewed when it does get it wrong.

knowing who caused you harm and why is necessary in stopping it from happening again.
in the real world, society depends on neighbors working together towards a common notion of the greater good.
if I live in a community that I depend on and I cause chaos, I will feel the consequences.
if I am a foreign agent, I am decoupled from those consequences, and may even benefit by virtue of undermining an enemy.
if the bad actors out weigh the good actors, then society cannot function.
and if you see your neighbors as being as bad as your enemies, then your enemies have truly won.
But if we can accept that there's not "right" without "wrong" or a coin's "tail" without a "head", we can sympathize with those we deem unworthy of "free speech".
Also, believe it or not but there actually are people who believe the Qanon nonsense. It's been widely reported on.
A very material number of people believe in that stuff.
More broadly - misinformation is very real.
It's 'silly' to believe that somehow the truth rises to the top. People believe the story that makes them 'feel' a certain way, and will deny the reality in their faces.
I'm on RT and watching Russian commenters indicate that all the 'dead bodies in Bucha' (near Kyiv) were Ukrainians killed by Ukrainians as a 'false flag'. Others say it they are not real. Other say actors. Others say it doesn't exist.
In 2022 you can just make up your own reality and spread it on Twitter, and that's dangerous.
We've seen from the past 4 or so years with QAnon, anti-vaxers, flat-earthers etc, that free speech to the wrong listener can be weaponised. If you make twitter censor-proof, all you'll get is a bigger trash fire.
I was sad when I got kicked off Twitter, but it possibly ended up being the best thing for me. Damn twitter is a toxic place... and if Elon turns it into censor-proof cesspool, I give the platform 5 years tops before it becomes yet another social platform that nobody uses anymore.
