Sometimes its about opportunity. I've been using Telegram for years with just a handful of people (and a bunch of bots...love Telegram's API). About 8 months ago my niece discovered that WhatsApp was owned by Facebook (so uncool) and switched to Telegram all on her own. I took that opportunity to onboard my mom and sister who then brought on some mutual friends. And just like that...WhatsApp was gone from my phone! This new agreement might hatch similar opportunities.
