Def agree that the vast majority don’t care about E2EE (though that’s probably growing with more news articles like that one where they went after someone for abortion and got their Facebook messages to prove it) I think it’s less about blue/green and more about how shitty the interop is. I don’t know anyone who is like “I won’t talk to green bubbles” but I know plenty who get annoyed when it fucks up the group chat or either side is stuck looking at a postage-stamp sized grainy image (if it even gets delivered.) Really, really blows that the predominate message services in the states are Apple-only iMessage, owned by Facebook, or SMS. I’m over 30, so I am not on Snap and most of my friends aren’t, I refuse to use Facebook products, so we’re stuck with SMS.
