I feel like I've invited everyone in my family to go on a great, grand vacation away and I'm the only one who's packed.

From their perspective, you're the fringe idealist who wants to move to a strange, remote place because of nebulous political ideology they neither understand nor wish to understand. And you are proposing that they uproot all of their preexisting social connections, support infrastructure, comfort, and familiarity to come live with you out in the middle of your scary, unfamiliar dystopia. Or, at least, force them to book a redeye flight and stay at a suspect hotel every time they want to visit you.

And honestly, you really are the fringe idealist here. Look at where you are posting this. Look at how few of us there are. Look at how many hoops you needed to jump through to set up what you have now. I certainly don't think you're wrong to champion privacy-focused ideals, but it absolutely is, strictly speaking in a populist context, extremely weird. It is weird to want to understand computerized tech, to know what it actually does, and to make bold, against-the-grain choices based on that knowledge. This is the unfortunate reality, and you have to make your peace with it.

I really do think your option is binary here. Join 'em, or cut 'em. Once you've shot your shot to convince someone to be more consciencious of their privacy and to take action to better secure it, and they frustratingly decline, that's it. They are not coming with you. Further pressing the issue will just drive a wedge between the two of you. At that point, the choice is yours. What's stronger, your willingness to stay conected, or your principles? Are you so rigidly disciplined that you're willling to cut ties (at least, through these channels) just to keep it? If so, I guess that's just a reflection of how much your principles really mean to you. If not, well, it's SMS/RCS and Google Docs for you.
