no, it makes the people who recommends the switch (to their non-tech friends) look bad. The majority of people don't care about these sorts of issues regarding privacy or open-ness. "Normies" care about the usability, reliability and speed.

I had convinced a few (non-tech) friends who used to use whatsapp to switch over to Signal. Then signal went down, and they immediately switched back, and that downtime made it look like i made a bad recommendation. Signal also has a bigger spam problems than whatsapp (you get these fake Amazon people trying to spam/phish you on signal, which never happened with whatsapp). I will no longer be trying to get people onto signal, not because i don't like signal (i use it myself with friends that do remain), but alas, whatsapp is still the "main" messaging app.

So in all, the dominance of whatsapp is due to their reliability and momentum - no amount of privacy intrusion is going to change that. So signal needs to up their game, but i fear the opportunity has passed already.
