I suspect these effects might also be very regional. Some anecdotal evidence from my end is that with the change of terms nontechnical friends are much more open to use other messengers if I say I don't want to use WhatsApp. Previously I was sort of regarded as the guys who was making a fuzz out of nothing, now people just say OK let's try. I suspect this is because it made it to mainstream media, so there is more general awareness. It seems also that the people moving now are more the nontechnical audience. For example my partner who is completely nontechnical and using what others are using, just told me last week that suddenly all her acquaintances are popping up on signal.
