Agree with your point, and email does succeed here just because it's ubiquitous. You don't need to check do you what whatsapp? Telegram? Oh I don't use this or that because of privacy, etc.

Email give you a FREEDOM to use anything you want with it because it was developed at times when data farming wasn't the main goal for big tech.

That's why in most cases we just ask for email address.
