I am not shocked. Ate you shocked that fb profits from mayhem? No because we know the character of the founder. Airbnb also has no moral character thus it's users also know they can profit from morally corrupt practices.
Just as you said, the whole stack is corrupt. There will be more of this to come.
They profit by knowingly breaking the law. They are criminals.
It is appalling that this can happen in a country built on a system of laws.
