Well, they thought it was the former (in part because of the ways in which it was the latter; a sustainable public service not provided directly by government typically involves payment from the government to the service providers.)
Much of the collapse and withdrawal is due to payments they were mandated under the ACA not being funded by Congress (resulting in a giant stack of lawsuits and at least one $200 million+ judgement against the government in favor of an unpaid insurer), with the deliberate intent of causing a collapse of just the kind that is occurring. (And the recent acceleration is that exacerbated by additional uncertainty deliberately injected by the Trump Administration with the intent of producing exactly that result.)
