Would the donor behind the Signal Foundation, Brian Acton, one of the WhatsApp founders who disagreed with the Mark Zuckerberg model of the internet, support the use of his donation to make threats or engage in legal proceedings against "non-official clients". Are there any statements from him about "non-official clients". Mike Benham ("Moxie Marlinspike") is no longer running "Signal Messenger LLC".1 Signal Foundation and its subsidiary Signal Messenger LLC appear to be the entities that control the Signal trademark. For example, the US service mark "Signal" is now registered to "Signal Technology Foundation", not "Whisper Systems LLC".
