Weird comment, no? Who is this playing too? This is a concern who exactly had before and why? My main guess would be that internal teams were saying: we need to moderate or we'll get booted. And this is the reply to the unasked question. Without context it seems unhinged.
Twitter is currently having trouble making Twitter (and always has), so there is a 0% chance this will happen. There's no appetite to give Musk more debt at this point, so he has no way to fund it.
This is one of those things, and there are many of them, that Elon says strictly for attention, not because he believes it or has any intention to follow through with it.
