> Aren’t there more ways how and more places where you can speak out today than ever before?

No. There was for a little while, but the number of avenues that one has for publishing unpopular speech are at a major low vs 10 or 15 years ago.

Now, the internet has reached the status quo of broadcast media prior to it: a small handful of gigantic powerful organizations have total veto over what can be published.

I'm pretty confident that, no matter what idea you want to express, you can find a forum on the Internet which allows you to express it. Even the most offensive, socially toxic ideas typically have a handful of forums that welcome them. Am I misunderstanding your argument here?

You can't find one that allows you to publish at scale. Screaming alone or in a tiny venue is very different than being able to publish to millions.

Everyone's words and ideas should be able to live or die on their own merit, and not be bottlenecked by shitty hosting and blanket domain bans in posts/DMs.

There are tons of places where you can post stuff; Facebook will happily censor DMs between consenting adults that contain your domain name when they want to share links to your content to others.

Become too unpopular (or, more accurately, increase in popularity too much with the "wrong" people) and your host will cancel your account. There aren't that many datacenter operators.
