@Inna22 I can sympathize with your dilemma here, but it's pretty clear that Airbnb (and most other businesses that have been blindsided by the scope of this crisis) do not have a long-range plan in place that would give you a satisfactory answer. And even if they did, there are just too many unknowns involved - we're in a whole different world now than we were a week ago, and we're nowhere near the top of this acceleration curve.
Here's what I would deduce regarding your post-April 14 bookings. Even if Airbnb were to overhaul the EC cancellation clause in the future, it would still apply to pre-existing bookings made up until that point. Without question, they will continue to refund guests who are restricted from travel and unable to complete their journey. The number of people that encompasses increases dramatically by the day, every time more government restrictions are announced, flights are canceled, and freedom of movement curtailed. Some localities in Europe are already implementing measures to ban the rental of short-term accommodation for non-essential purposes. By the time the spread of this pandemic catches up in the US (as it inevitably will in a matter of weeks) you could be looking at this or even stricter measures. By the time April 14 rolls around, my prediction is that all of your bookings will be eligible for EC cancellations even under the terms that were in place before the COVID-19 amendments.
The harder thing to guess is how far-reaching the effects on travel will be after restrictions are lifted. Even if the infection curve has flattened by June, the economic and psychological effects of the crisis will still be reverberating for a much longer time to come, and a new set of laws and norms affecting borders and transit might be in place in perpetuity (for Americans, the aftermath of 9/11 is a closer reference point than any modern pandemic).
If shifting at least some of your units into long-term housing is what it takes to protect your livelihood from these devastating uncertainties, that is what I hope that you do. Perhaps there are ways to split the difference and still keep one foot in the hosting game.
