On its 10th anniversary, Signal’s president wants to remind you that the world’s most secure communications platform is a nonprofit. It’s free. It doesn’t track you or serve you ads. It pays its engineers very well. And it’s a go-to app for hundreds of millions of people.
Just to add to this, I also like to use the “donate for a friend” option to gift friends a donation to Signal on their birthdays. It’s also $5 but a one-off thing, they get a neat badge for 60 days and perhaps it raises awareness of the donation option a little bit!
