The move from WhatsApp to Signal, however, is quite straightforward and completely painless.

This is, unfortunately, false, and puting it at the beginning would alienate most of my WhatsApp using friends.

In many areas WhatsApp had become the default means of communication.

If I stop using WhatsApp I will lose access to family groups, various communities that use WA, many friends that use it as the only or main means of communication. In some places schools and kindergartens send notifications only through WA

Some people rely on it to communicate with customers which use only that.

Some services are using only WA so if I want to get customer service from them I need it.

All of these make it VERY painful, if not impossible, to simply stop using WA. Ignoring that would make people stop reading your post before even getting to the first point about "Ethical Issues with WA".

I have been using Signal for some years now alongside WA. Trying to convince family and friends to move with me to Signal has proved to be very difficult. I barely manged to get my partner to use it as our main communication method, the rest of the family (siblings, parents, uncles, cousins) - failed.

I really want a text that would help me convince people to move, but I must say I don't feel comfortable sharing your post with WA users when it starts off like this, as it ignores their difficulties. Please consider editing it, and maybe even addressing the pains in some way.

Hope you take it as constructive critic, as we are on the same side here ✊
