Totally empathize with all the comments here, and we are not trying to defend Airbnb's decisions. We personally do not agree with this decision, but I'm certain they weighed the pros and cons and decided this was logical for them to do. Only time will tell if it was the right decision.
Being a business owner involves a lot of risk management, and relying entirely on Airbnb for income is a huge risk for obvious reasons. For one, you'll be exposed to their decisions (good or bad). The point is that Airbnb does not own your property, they are just a resource, don't forget that. There are ways to mitigate this risk, too, and creative owners are already doing that.
