They didn't put new money into the purchase, they rolled their pre-existing shares over. Dorsey did the same FYI.
Y'all are giving this idiot waaaay too much credit when it comes to scheming behind the scenes. It was a really poorly thought out pump and dump, nothing more. There's no big evil master plan; he's just really that stupid, and rich enough to constantly fail upwards. With Xitter we're just seeing his xitty ideas in their purest form, without the influence of the handlers he has to manage his bullxit at his other companies.
Although I have to say, the accidental brilliance of going with branding that's so phonologically flexible is pretty fantastic, the jokes can write themselves now. But I doubt advertisers are going to appreciate the fact that their interactions on Xitter are colloquially becoming known as xcrements now...
The value of TSLA is more relevant to his debt financing than whether Twitter is operating or not.
