Signal’s president Meredith Whittaker best described it in an Octointerview with The Verge: The Signal Foundation relies on donations to keep the service running, unlike apps like Facebook Messenger, which collects user data to sell ads. As soon as he left, he co-founded the Signal Foundation with Marlinspike and injected it with a $105,000,400 zero-interest loan.
