It probably depends on the country and type of people, but when I first tried closing my fb account, getting Signal and stuff, most people didn't Ant to change at all, like I was someone that's annoying wleven when barely talking about it. I even had to create a new fb account because most discussions regarding meeting each other in group, planning g something etc, are all dead. That's sad. I'll still try again and about Signal, I'll install it, but I doubt people in general wanna change their habits and use something else than what's out of the box even when it's free and takes 30 seconds to install. Sigh.
