Instead of an authoritarian government forcing "ungood" into our vocabulary, we've got companies pushing "unalive" into our vocabulary, at least in online discourse. If this fervent content blocking becomes an industry-wide practice, there won't be much that separates us from the language regulation in 1984.

So what, we just hope that Twitter doesn't give in?

I'm a decently young person who spends a lot of time on the internet and I don't recognize virtually any of these terms. I would certainly raise an eyebrow if someone used any of these in conversation with me.

Is this actually affecting how any people outside the tiny demographic of "some popular content creators on some social media networks" speak?

People finding creative ways to get around censorship is nothing new, people talked like this to get around chat filters all the time in multiplayer games I played as a kid. I feel like people only think it's interesting now because mystical "algorithms" speak to the imagination

I agree with all the comments here and would like to add that this really isn't anything new. Back in the 2000s with the onset of Livejournal/AIM/Tumblr/Memes 1.0, we saw a similar kind of "internet language" develop as a form of codespeak or shibboleth communication for the in-crowd. Granted, in this case the motivation to create this language is for a different purpose: to get around algorithmic censorship.
