During the time you were that, my son's daycare provider joined Signal. The network->tsunami effect is real and is currently happening in Switzerland. WhatsApp has burned their bridge to Swiss society, somehow. Shocking, but welcome.
WhatsApp has near-total market penetration in Switzerland. I hope this will change now, at least a bit. Until recently, you'd get strange looks if you mentioned that you don't use WhatsApp. (People sometimes assume that means you don't own a smartphone.)
The whole situation has seen mainstream media attention here, which helps a lot I guess.
Of course. I was talking about an entirely different place with huge differences — from education to value of life (which is close to zero IMHO).
