It hasn't changed a whole lot since most people are KYCed by phone companies. I was screwing with a coworker over text and his wife figured out who I was in about 3 minutes. In fact, it's probably worse since I can't opt out without using tactics to conceal who I am behind the number.

It isn't super practical to avoid this yet given how much stuff they're tied to. I could probably with a lot of work and frustration.
