I think most people here would agree that allowing suspension of monthly payments until the parks reopen would be a solid token of goodwill by Disney. Especially as the potential for decreased visits exists, maintaining good relations with the local base is a great idea. And from a human compassion side, would fit alone with the "everyone helping out each other" mindset that we'd all like everyone to exhibit in this time of need. Disney as a massive corporation can afford it, even with their current financial state and its a reasonable request for them in light of the chaos going on in this country, especially as their peers do it.
That said, I do see from some posters the idea that Disney is "wrong" by not automatically deferring such payments, seemingly under the premise that they "can't use the pass now". This, I would argue, is simply incorrect on the basis of what everyone has mentioned - this is a monthly installment payment just like an auto loan. Disney is under zero obligation to not expect to have monthly payments continue as scheduled.
And, quite frankly though I'm sure some will call me out on this as being too cynical, I would think if you can't afford the monthly payments on an AP due to a loss of income for a month or two, then you probably shouldn't have been buying one in the first place. If you don't have the cash on hand to pay off a luxury good at any time without adversely affecting your fixed expenses then that's a luxury good that you can't afford.
