You can't control or convince others.

What you can do is live your best life and let them know it. Not in an annoying way, but in a real way.

How many conversations do I hear about spam calls or text messages? Everybody hates them and they get in on this commonality thing of yeah we all hate that it sucks. Then I bust out with a, yeah I'm glad I don't really deal with that anymore... Wait what? I have a solution?

Then I break it down, and I'm very clear my measures are not for the faint of heart. But its a spectrum and there's some low hanging fruit they can do to dramatically change things from where they are. Do they do it? No. But they now know there is a better way and acknowledge it, then actively choose not to do it.

Does that change anything? Yes and no. No, nothing technically changed. But yes, they understand a little more now. So now they don't treat you like a crazy person or if you say you'd rather not use WhatsApp or whatever they aren't so insistent that this is all you being weird.

Stop making it a confrontation is my point. That makes you the bad guy. You're not, the companies and governments are. Let them see that.
