Absolutely, that's why people like you and me (who care) should put in the effort to try and influence those around them. Once enough people do it, and once it's cool to do it, it'll happen.
Not trying to be an arse here but just because our group of people do it doesn't mean it'll ever be "cool" to do it. It may get cool in our "techy" circles, but i highly doubt our less tech savy peers will come around any time soon.
Heh, no, fair point (and not what I was suggesting). I just think that Signal is a drop in replacement for WhatsApp and it can start a conversation about privacy and what happens with data.
I didn't say initially that I meant Signal more as a straight replacement for Whatsapp, not FB.
