I honestly don't think they care. The OP's already done what they want, which is to make a stink. We all do what Musk wants by talking about him when we really should just be ignoring him.
It was a dead-end situation as soon as OP agreed to limited liability in the Twitter TOS - sure.
If you want to cause damage though, their insecurities are plain as day; they need user retention. That's why they reach out to butter-up long time users with new account offers and bespoke transitional options. This is your one chance to tell a human at Twitter you're done. That because of this situation you've been put in, you're going to abandon the platform entirely. Take it or leave it.
Sure. It certainly won't help X. Maybe it will cause them to think. I think they're so far in their own world they won't notice it's all burnt down until MUCH later.
