Unfortunately I have also found it to be a huge impediment to making friends with other millennials who aren’t techie. I sort of left a crowd that was always on xmpp and signal and found myself rather ostracized.

But unfortunately passed explaining why you won’t support Meta, and why alternatives like Signal are good there isn’t much to do.
