The whole e-mail thread linked to discusses this change in details, in particular in terms of what it means to open source software and what potential remedies are left. The Banktivity links are, in turn, of little value to the open source community as is. Typically, when a mailing list e-mail is submitted to HN, it's rather the whole thread that is worth reading for the context, not just the very first e-mail in chain.
