Maybe they aren't but they are very vague and hand-wavy about the "blatant censorship". Without specific examples of what is being "censored" it's incredibly difficult to have a good-faith discussion on this. I'm much more forgiving of a handful of on-the-line or even "decent" content being removed if it's the exception not the rule. Like it or not a ton of moderation is fully or nearly fully automated since there isn't a viable alternative (You can argue that these companies should be allowed to exist if they can't accomplish human review/moderation, I'm speaking to the current reality).

I'll also be the first to say that Twitter (and most) moderation isn't 100% evenly handled. Just look at world leaders/political figures and what they can say that others cannot, I fully agree this is not ok and should not be allowed. My issue is that it's to the point that I can't hear "blatant censorship" in connection with social media without hearing the dog whistle. Those people who are so up in arms about FB/Twitter/etc "censorship" seem to be absolutely silent about the Gab/Parlor/Truth Socials of the world.
