This is the platform that led to the proliferation of newspeak terms like "unalive" to circumvent content restrictions. Such speech restrictions were never a thing on FB, IG, X, or YT, yet this form of self-censorship has spread to those platforms anyway, because TikTok users have become so used to it.
While there aren't direct speech restrictions in platforms like YouTube, you're leaving out the crucial detail that mentioning words like "suicide" gets your video demonetized, which directly causes similar self-censorship.
YouTube pays creators based on advertising deals making some topics far more valuable, while other topics have become very sensitive to advertisers. That’s related, but different from censorship.
Creators are still free to use YouTube as a platform to discuss sensitive topics with a very large audience without paying per viewer, unlike say advertising or standing at a street corner talking to passersby. As such YouTube is still supporting the discussion and distribution of said content.
