Dont you think that maybe you are taking things a bit far if you are losing lots of friends over it? What's your threat model?
You can bridge a number of these services if you want. Or use a locked down device for them. FAANG privacy crap causing you to lose friends is kinda letting them win a bit too much.
Bah, what friends are they that ignore someone because they don't have Facebook or believe in a better future for everyone. Better off without them, in my opinion. As I mentioned, they just move on to the next worse thing and the cycle of stupid choices continues.
I have mixed feelings on this. One the one hand, yes, true friends will use smoke signals to reach you if needed.
On the other, like you, I’ve missed many events of people I like but am not that close to, because everyone is on WhatsApp, why didn’t you come, oh, right, you’re that one guy.
Eh what about maybe they have a different threat model to you? Maybe they have elderly relatives who just about switched from SMS to Whatsapp and they want to talk them in an easy way?
The most secure communication is the communication that doesn't happen. He can be pretty sure his communication channel will not be abused by some big advertising corp.
