Seriously stop harassing me.
You have no idea what you are talking about. Re-read the TOS we all agreed to. There are two options. In technical legalese, choose either: a.) Take it, or b.) Leave it.
We don't have a 'contract' with them. Where are you getting that idea?
You can't sue them. You can elect to participate in binding arbitration to address a dispute, and lots have. Many have even prevailed.
Hosts may have lost business from these changes, yes. I am even one of them! It's unfortunate but there is literally nothing we can do about it. Except hope that maybe Airbnb will come to their senses and rework some of these radical changes they made to the platform. But if it happens it won't be because a few hosts whine. It will be because they are losing revenue on service fees due to a search and booking process that is too confusing and error-riddled and customers are going elsewhere where it's easier.
But we have no grounds to sue Airbnb, who has always claimed they were merely a listing platform and have created a TOS that makes certain you don't. It would be like suing Craigslist.
But since you seem to be an attorney and know everything about 'rights,' by all means sue them. A billion dollar company versus little ole you. Better have some time and money to litigate too. Let's see how far you get.
And stop harassing me.
