Part of it's normalcy bias, another part is just the parts of twitter we engage with. Lefties are increasingly complaining that the site's now a lot more right-leaning - they're detached from reality, of course, but I have noticed that anything in the normiesphere is no longer censored - you can call out fraudulent elections, jab stuff, and so on. Snapping your fingers and purging a bunch of IC alums from a very complex system isn't as easy as all that - he could be doing more, sure, but it's not trivial.
