Ownership of identifiers, that includes usernames, is regulated by Trademark laws.
If you keep using a moniker, like a username, to conduct trade under it, and/or have it registered as a trademark (which requires you to use it in trade or lose it), then you can legally claim it.
Otherwise, Twitter or any other platform, can do whatever they want with it.

That’s an interesting avenue I hadn’t considered. However, the lack of a registered trademark does not mean the lack of any rights whatsoever.
