I know it's de rigeur to assume incompetence, but there are real journalists out there. We don't have to galaxy brain everything.
The story was posted on 12/13. Even if you blanketly assume 1st of the month is when rent was due, which may or may not be the case, one of those did pass. They're probably withholding rent to try to renegotiate their leases or something.

Twitter has to be in chaos technically simply because they don't have the staffing required to upkeep an operation that big. No one has any idea if a catastrophic failure will happen, when that would be, or really a goos feel for their remediation capabilities given the staffing cataclysm. We do know they have managed to do things like lose access to some of their internal code repositories. If you know whether that will actually bite them in the ass in a significant way, buy a lottery ticket.
FWIW I did Pin my Mastodon to my professional Twitter because I moved platforms. There were plenty of people being dramatic, but also people just trying to keep in touch with established communities. Of course these are technical people, so they automated the process. Pinning and bio was done because that worked best with the automation method most people used.
