Right there with you, it can feel terrible when you present something so easy to do and important to you ( signal is a very good app in absolute terms ) and they brush it off.  Stay strong friend.

To be honest, at some point you just have to do the switch if you care enough about your privacy by deleting the messengers you don't want to use.

I was there too. No amount of convincing is going to change their mind. They have to make the decision which messenger to use themselves just like you do.

You may look like an asshole by moving away from the "common ground" but imo that's worth it. They don't realize that they are the ones being disrespectful by valuing being lazy over your feelings of privacy.

How to convince fam/friends to get Signal

It's disheartening really, I've known these people for over a decade and they can't respect me enough to download an app. They don't understand how much we're being surveilled. And they're still in the nomie mind virus of nihlism and "I have nothing to hide"
