I have been on Twitter for a decade, and I've never been reported. I can speak my mind as million other people.
Twitter has in fact a very mild moderation: sometime you report things, and rarely Twitter blocks someone for a period of time.
This is to say that you can really use Twitter as you please, right now.
Elon always talks about free speech online, never about fighting disinformation or hatred.
Which are, to my understanding, exactly opposites.
In fact, critics from the left are all about this: "freer" speech online often means more harassment, racial slurs, insults, rape jokes, you name it. Have you have looked at the "free speech" places online like 4chan, Reddit /pol/, 8chan? The ones where you can write anything you want and conspiracy theories like Qanon and Pizzagate are born and are cultivated?
Your eyes will melt. They were born exactly because other online places did kick them out: they are quite often the cesspool of humanity, where you can find all the worst stuff you can imagine. I encourage you to read about Fredrick Brennan, the creator of 8chan:

Maybe this is a generation gap: I understand people here are US-based, in their 50-60s, and of course we have a very different experience of Internet (and the life in general).
I just think (with a 20 year online experience on my belt) that platforms and software are very, very important, but nothing can fix how people communicate if people don't want to fix it themselves.
Even this tiny forum is moderated! If I were to insult everyone and make rape jokes about your families I'd be rightly blocked and banned in an instant.
Nobody really knows what Elon will do with Twitter, and I'm in favor of some ideas he mentioned.
But the "free speech" part gives me pause for the reasons I tried to outline.
