Guerrillamail.com is about to lose their .org domain registered since 2006

Hello, Guerrilla Mail is in imminent danger of losing the http://guerrillamail.org - a domain registered since 2006, all because a single entity has decided that Disposable Email is "harmfull for the internet"

Are there more details on this? There must be more to it than a disposable email. There are many single-use email domains currently in use today.
