You've got as close to absolute free speech as you'll get, so long as you exercise it where no one will hear you (i.e. town square or middle of the forest).

A step away from that would probably be 4chan, but you might actually reach the same amount of people as the middle of the forest, since reading through all that noise is a huge pain.

A step away from that is probably Twitter since April 2022, when Elon Musk started shining a light. You either need followers or a well-placed comment, but if you're a real person, you can probably say what needs to be said.

A step away from that is probably the Alex Jones show. Just like 4chan, you've got to watch so many bad interviews before you get one worth entertaining, and even then there's doubts.

I guess it really depends on what you have to say and who you're trying to get to listen. Seems you can criticize any group of people here on Saidit, rightly or wrongly. What do you need to get off your chest?
