X does have a vested interested in ensuring its usernames and accounts do not legally become alienable property that can be auctioned in a bankruptcy auction. They don’t technically allow accounts or usernames to be sold at all (or follows, engagement and so forth), although I’m sure this happens quite often under the radar. X can and has taken any username they want away from a user for any or no reason. Filing a brief in a bankruptcy auction that “this property is ours, not the debtor’s, and may not be auctioned or also” is an obvious way for them to publicly assert their rights and ownership.
