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.
I see that as offering services that people clearly use and value, and that the bills have to be paid somehow. So as long as proton can deliver the privacy and security features it promises, I personally don’t see anything wrong with providing an alternative when the only other options are built on monetizing your data.
