That wasn't the claim. The claim was that people aren't leaving voluntarily, which simply isn't true. Lots of people have voluntarily left Twitter since Musk took over (About 23% DAU, a ~50 million drop) and that's before Brazil banned it

That people are also leaving because of twitter being banned in their country isn't relevant to the original claim

Your response is a non sequitur; adding on to GP’s comment, countless people have left voluntarily and are easily findable on mastodon and bluesky, refuting GGP’s comment.
