As an aside, the fellow who started WhatsApp has a new app called Signal. The story, and make of it what you will, is that when he sold WhatsApp, promises were made that were altered after the deal was done and META purchased it (no surprises there). Once free from his non competition clause, he started Signal with the goal of providing what he believed he had created, and would be sustained, with WhatsApp.
Signal pledges:
"There are no ads, no affiliate marketers, and no creepy tracking in Signal. So focus on sharing the moments that matter with the people who matter to you."
"Signal is an independent nonprofit. We're not tied to any major tech companies, and we can never be acquired by one either. Development is supported by grants and donations from people like you."
"There are no ads, no affiliate marketers, and no creepy tracking in Signal. So focus on sharing the moments that matter with the people who matter to you."
