Don't give up : )

After some of my friends swiched a few groups, switching has happened naturally group by group since Telegram arrived and today I just have to struggle with my siblings and a local group that also contains a number of elderly people that I won't force to change.

(For those who are not aware Telegram is dimilar to Whatsapp but with less focus on formal verifiable crypto but with other advantages like not-owned-by-neither-Facebook-nor-Google, simpler anf more powerful UI, opensource, a choice of multiple clients, better desktop client, bot API etc etc. The lack of verifiable crypto is still an issue but as long as Facebook owns Whatsapp it seems crypto doesn't help too much :-/ )

i am not so sure here; Malcolm Gladwell says that social things depend on a small number of highly connected trend setters - i would think that these trend setters would understand the privacy requirement because they know that their influence is derived from trust (and trusted communication); Also privacy problems seem to be a major turning point where communication gadgets fall out of use.
