Elon is the CEO and owner of Twitter. When the Twitter office spaces are not being paid for its because Elon is not coming out of his own pockets to pay those bills.

Elon is the CEO but not the owner of Tesla. He is is a very large stake holder. Any bill Tesla pays or does not pay is part of Tesla's finances not Elons.

Tesla currently has 2 billion in debt down from 5.4 billion in 2021 which is also down from there peek debt which was 11.6 billion in 2019.

Say what you will about Elon. But Tesla has virtually no debt meaning their contractors are fully paid, and this has been true for 4 years.
