I understand after having read the explanation. However, my experience with chatbots is that they are unreliable, unhelpful and obnoxious, and I tend to go out of my way to avoid using them. I don't think a conversation is a right model for this. I also don't think it looks good when a website or app wants me to install a messaging app to create an account (though of course some people already use Telegram). It would have to be very enticing for me to overcome that friction.

The platform (Apple's, in this case) might be hostile to developers to some extent, but the whole web is hostile to users, in no small part thanks to websites slurping as much PI as possible and then leaking it one way or another. I get spam and phishing attempts every day, as do all of us, and I regularly see some of my burner emails show up on haveibeenpwned. Any service that helps me separate my accounts from me is some progress.
