I'm not sure why you'd delete them because some people might not be seeing them..? I'm very sorry you feel that is necessary.
What I believe is that Disney also expects some people to be more averse and that is why they are offering people they can't serve today a 25% bonus if they rebook within the next 15 months. They're trying to cut as many losses and hold on to as much money as possible for now. Since travel is going to stay complicated they'll likely double down on last minute CM offers, *GT, and resident only deals to help fill the ships as needed rather than offers to people who might have to spend a lot more money and hassle to get there. Summer is already a wash, and hurricane season/winter is typically when we see the most deals anyway. Cancelled cruises this year are helping fill up next spring break and summer nicely, probably in those higher categories too since people have "extra" money.
At the price point they've had their cruises for the last several years they might even luck out and their customer base might be in the higher income bracket of people who are relatively unphased by the current economy. Certainly folks in the UK and EU are faring better financially as their governments are providing more of a social net to people impacted.
If the economy doesn't improve enough for them to recover then maybe after the current round of vacations and bookings expire they might try something else - but they seem to be setting things up to try and hold out for at least a year. I suspect the next couple rounds of releases will be business as usual while we all wait and see what happens longer term.
If cruising can even continue as it had... of course.
