How Does Signal Work As A Non Profit?

Signal does not show ads, or charge users a fee for being on the app. So how does the platform plan to make money? According to Signal co-founder Brian Acton, donations and grants are its business model, much like Wikipedia. "Part of that's growing the users and making sure that we have enough donors to work with and then, of course, giving them, you know, a reasonable tool to give us a donation if they prefer," Acton said.
