It makes sense why they want to do it but it's really sad. I think you still can use the majority of privacy-respecting internet if you host your own email (so you don't need a phone number to register it) but it basically reverts the internet to the 90s because you need knowledge to set up a server and it doesn't let you use almost all of the popular messenger apps, making usage of the "official identity" mandatory to contact most of the people and therefore lose privacy when the situation gets worse
