None of the people I had on WhatsApp think like me. They're mostly just my family and relatives. But I told them "I'm quitting WhatsApp, if you need to message me, use Signal". And they all just downloaded Signal because it's honestly not that big of a deal. It's just another free chat app.
"It's not how the world works". Of course it is. Most people downloaded WhatsApp because someone told them to so they could message each other.
It isn't how the world works. For change there needs to a value proposition. Your entire proposition is it fits your personal views. Why do you expect others to change for your personal choices when you aren't willing to change for theirs?
You essentially have a personal disagreement with the practices of a specific company and want to inconvenience others who might not think the same way. It's arguably a selfish perspective, family members may be willing to bend to those demands for an individual. But to expect businesses to indulge every single individual preferences for how they wish to be contacted is impractical.
