My two favorite things about this "article" is that in the very FIRST bullet point she admits she pulled this out of her ass and my other one is that there is not one (1) quote from an employee blaming the bank's collapse on WFH policies. Didn't see any in the article she was referencing either.
She's literally just saying it out loud.
The point of the article is to give employers something to point at as grounds for terminating WFH, that's literally the stated purpose of this article's existence, and she's just saying so out loud.
