Overall the major crisis was a sort of A owes B owes C owes A... situation, massively scaled up.
So the Fed provided a number of guarantees to resolve that situation ("We'll arrange for B to get a loan so they can pay F, R, W, and C, then C can pay A but they need this much extra but they'll get it from Y and P..."). It isn't, in and of itself... 'evil'... per se. But it is wallpapering over a mess, and allowing the source of that mess to fester, and return in however long, rather than allow us to examine and correct the core problem.
Either that.. or something that had it been disclosed within a certain period of time would have been fiscally advantageous to some.
There are rumors to that effect, for sure.
