The radical platform alternatives still censor and often to the whims of a random person. It's like a reddit subreddit or wikipedia article: you are censored by the moods of the admin. They are privately owned.
The solution is easy; host your own instance. Federated solutions let you put your money where your mouth is and host yourself to your own content. If what you have to say is considered useful, you'll be a viral figure in no time.
Allow-only instances won't show your content but chances are they won't show most content. These are hugboxy environments you'd probably not want to be around anyways (and they sure don't want to be around you).
Block-only instances will show your content as long as it doesn't piss them off. If you are being racist or posting illegal content, you're gonna get muted. They have absolutely no obligation to propagate your content if you're not going to reach bare-minimum decorum.
