Copying my comment from another thread:

But they’re not just re-branding. Twitter is now under some kind of corporate shell company. I haven’t seen much coverage of that, but my suspicion is that it’s intended to act as some kind of insulator to contain Twitter’s debts.

Like when they break a company into pieces and put everyone’s debts and no assets into a single part and then that part declares bankruptcy and all the debt magically goes away, leaving everything else with lots of assets and no debts and a future that looks really rosy. I can’t help but think that this is something similar to that.
