That's not always the case. Sometimes it asked me for a phone number, but most of the time not when not using a VPN or something similar. But last year I managed to create two Twitter accounts with the Tor browser and some sketchy email address and never got asked for a number, just had to do some captcha after a few minutes.

I created a few twitter accounts this year for various reasons and all of them had the same number requirement after around 24 hours!
